Conduktor release notes

Console 1.31.1​

Release date: 2025-02-18

Console metrics performance and configuration​

To address issues related to monitoring graph timeouts and OutOfMemory issues when Console is connected with large Kafka clusters, we've introduced a change to how metrics are collected in Console.

This feature is currently optional but will be enabled by default in the next release.

If you're experiencing graph timeouts or OutOfMemory issues, upgrade to 1.31.1 and configure the following additional environment variables:

CDK_MONITORING_ENABLENONAGGREGATEDMETRICS: false
CDK_MONITORING_USEAGGREGATEDMETRICS: true

This configuration will disable the collection of obsolete granular metrics and use the new aggregated metrics in the Console graphs.

See metric configuration for details.

Fixes​

• Fixed dependencies vulnerable to the following CVEs:
  • CVE-2024-57699
  • CVE-2025-24970
  • CVE-2024-45337
  • CVE-2024-45338
• Resolved an issue related to SSL checks between the Console and Cortex where bad certificates caused communication issues
• Fixed an issue with user email addresses containing a ' character that blocked database migrations
• Reduced the memory consumption and improved the performance of metrics under heavy load that prevented them from displaying
• Partner Zones: configuration updates are now applied correctly
• Partner Zones: partners can now utilize consumer groups

Gateway 3.6.0​

Release date: 2025-02-12

Features​

Kafka Cluster connection management​

This release includes a set of enhancements to how Gateway manages connectivity to a Kafka Cluster. This provides greater stability and flexibility for how Gateway can be configured with the Kafka Clusters it's connected to, and is a precursor change for future product releases.

Encryption improvements​

Encryption Secret Id Mustache Templates​

The encryption now allows multiple mustache substitutions in a key secret Id configuration. Previously, only a single substitution was supported. E.g. This is now allowed:

"keySecretId": "vault-kms://my-vault:8200/transit/keys/{{record.key}}-{{record.header.someHeader}}"

Decryption failure modes​

This release adds a new optional configuration to the decryption plugin to allow different modes of handling errors. There are two supported modes:

• errorPolicy: "return_encrypted" Previous - if there's an error during decryption, then the encrypted data is returned.
• errorPolicy: "fail_fetch" New - if there's an error during decryption, then the fetch that was reading the data is failed and the client will receive an error.

In both cases, we have enhanced the logging, so issues during decryption are more fully reported.

Schema Registry access improvements​

Read only Schema Registry access​

Some of our Gateway plugins will deserialize and re-serialize messages in order to perform their functions. A side effect of this is that the serializer code would unnecessarily require write access to the Schema Registry. While there was no situation where Gateway would actually cause any updated or additional schema to appear, - we've altered the Schema Registry access to be read only. This avoids having to unnecessarily assign write permission for our Gateway Schema Registry connections if you're using ACLs on your Schema Registry.

Plugin validation of Schema Registry access​

All Gateway plugins which access the Schema Registry will now validate that the configuration for the Schema Registry is correct when it's added or updated in Gateway. Previously, this behavior was inconsistent and a few of our plugins would only detect incorrect configurations when they processed a message rather than when they were setup.

Quality of life improvements​

• Added a new CLI command conduktor run generateServiceAccountToken to generate the JWT for local service accounts. Update your CLI to version 0.4.0 or higher.

Fixes​

• Fix: CreateTopicPolicy and AlterTopicPolicy overrides. There were some edge cases where the desired overrides from the plugin config would not be applied. These plugins now behave consistently in all situations.
• Improvement: Removed some verbose logs and updated logging to be clearer. A general set of improvements has been made to Gateway logging, making some errors clearer and reducing repetition.

Breaking changes​

Removed V1 Alerts​

Original alerts created in the Monitoring/Alerts section are no longer available.

Changes to V2 Alerts​

V2 Alerts, that can be created since Console 1.28 on the dedicated resource page (Topics, Brokers, etc.) are still available and active, but have been migrated with the following rules:

• Alerts have been automatically configured with the previously globally configured channel (Teams or Slack).
• Alerts have been assigned to the individual who created them.

Read below for more information about the new alerting functionality.

Id of Certificates​

The Id of certificates in the public/v1/certificates API endpoints were modified to represent the fingerprint of the certificate. It brings a more stable way to identify certificates in audit log and prevent multiple uploads of the same certificate.

Scale​

Enhanced Alerting with Added Webhooks Support​

We have made significant improvements to the alerting system in Console.
Here are some of the changes:

• Alerts are now owned by individuals, groups, or applications
• We added Webhook destination to alerts notifications
• Destinations are now configurable per-alert
• API / CLI support for Alerts is now available

apiVersion: console/v3
kind: Alert
metadata:
  name: messages-in-dead-letter-queue
  group: support-team
spec:
  cluster: my-dev-cluster
  type: TopicAlert
  topicName: wikipedia-parsed-DLQ
  metric: MessageCount
  operator: GreaterThan
  threshold: 0
  destination:
    type: Slack
    channel: "alerts-p1"

Alert creation workflow has been updated to allow you to configure the alert destination and ownership in the UI.

Read the alerting section of our documentation for more information about the new alert functionality.

API / CLI support for Service Accounts​

We have added support for Service Accounts in the API and CLI.
Declaring ServiceAccount resource lets you manage the ACLs of a service account in Kafka.
At the moment we only support Kafka ACLs (calls to Kafka APIs) but we plan to add support for Aiven ACLs in ServiceAccount resource in the future.

---
apiVersion: v1
kind: ServiceAccount
metadata:
  cluster: shadow-it
  name: clickstream-sa
spec:
  authorization:
    type: KAFKA_ACL
    acls:
      - type: TOPIC
        name: click.event-stream.avro
        patternType: PREFIXED
        operations:
          - Write
      - type: CLUSTER
        name: kafka-cluster
        patternType: LITERAL
        operations:
          - DescribeConfigs
      - type: CONSUMER_GROUP
        name: cg-name
        patternType: LITERAL
        operations:
          - Read

Labels support for Service Accounts​

We have added support for labels in the ServiceAccount resource.
For now you can only edit labels through ServiceAccount resource in the API and CLI.

---
apiVersion: v1
kind: ServiceAccount
metadata:
  cluster: shadow-it
  name: clickstream-sa
  labels:
    domain: payment
    region: EMEA
    application: clickstream
spec:
  ...

The labels are used to filter the Service Accounts in the UI. Editing labels in the UI will be available in the next release.

Self-Service support for Application Managed Service Accounts​

We have added a new mode for ApplicationInstance that allows Application Teams to have full control over their Service Accounts.
This mode can be enabled in the ApplicationInstance with the following flag spec.applicationManagedServiceAccount set to true.
When enabled, Self-Service will not synchronize the Service Account with the ApplicationInstance and will let the Application Team manage the Service Account directly. Application Managed Service Accounts can be declared in the API and CLI using the Application API Key.

---
apiVersion: v1
kind: ServiceAccount
metadata:
  appInstance: "clickstream-app-dev" # Mandatory to link the Service Account to the ApplicationInstance
  cluster: shadow-it
  name: clickstream-sa
spec:
  authorization:
    type: KAFKA_ACL
    acls:
...

Application Group permissions now available on Users Permissions page​

The users permissions page has been updated to show the permissions inherited when they belong to an ApplicationGroup.

Exchange​

Exchange is a new Conduktor Product aimed at helping you share your data securely with your external partners.
Check the associated Exchange Product page for more information.

Introducing Partner Zones for Third-Party Data Sharing​

Partner Zones enable you to securely share your streaming data with external partners, without needing to replicate the data into a second, physical Kafka cluster.

In the upcoming releases, we will be adding the following:

• Dedicated pages that allows you to manage Partner Zones completely from the UI
• Support for Traffic Control Policies to limit the amount of data that can be consumed or produced by your partners
• Topic renaming capability to avoid leaking internal topic names to your partners

For more information, check out the Partner Zones documentation.

Quality of Life improvements​

• Added a "Groups" tab in the Application page which shows all of the Application Groups created via Self-service
• Improved the license plan page to show the start and end date of the license, as well as the packages included in the license
• Added the remaining days left in the sidebar when the license is expiring in less than 30 days
• Improved how a connector's configuration is displayed in the raw JSON view by sorting the properties alphabetically

Fixes​

• Fixed several issues Confluent Cloud Managed Connectors
  • Fixed Pause/Resume connector
  • Fixed Connector and Task Restart
  • Fixed Connector Status (Running, Paused, etc.), previously displayed as "Unknown"
• Fixed a permission check issue when adding partitions to a topic

• Fixed an issue parsing masked data when choosing the String format on data that cannot be parsed as JSON
• Added topics ending with -subscription-registration-topic and -subscription-response-topic to the Kafka Stream filter
• Fixed the edition of ownership mode of application instances
• Fixed the form for saving producer templates
• Fixed the navigation to go back to the home page of connectors when switching clusters

Known issues​

• We are aware of more inconsistencies with Confluent Cloud Managed Connector support in Console. We are working on it.
  • Task status is not always correctly displayed
  • Various UI responsiveness issues

Gateway 3.5.2​

Release date: 2025-01-17

Features​

• Add support for sourcing environment variables from a file

Fixes​

• Add automatic refresh of HashiCorp Vault authentication tokens

Console 1.30.0​

Release date: 2024-12-16

• Features ✨
  • RBAC support for Conduktor SQL
  • Add support for multi-hosts database configuration
  • Delegating authentication to an identity provider
  • More Audit Log CloudEvents into Kafka
• Quality of Life improvements
• Fixes 🔨

Features ✨​

RBAC support for Conduktor SQL​

In a previous release, we introduced Conduktor SQL. It was restricted to Admins because it did not apply any permission model.

This new update brings full RBAC support on Conduktor SQL:

• Users & Groups can only see and query the tables for which they have an associated Topic permission in Console
• Data masking policies are applied (with limitations)

You can now bring SQL to all users within your organization.

For more detailed information, check out the SQL security section.

Add support for multi-hosts database configuration​

You can now setup Console's backing database for high availability(HA). If you have a PostgreSQL HA setup with multiple hosts, you can now configure a Console to JDBC connection to the database using a list of hosts.

CDK_DATABASE_URL: jdbc:postgresql://user:password@host1:5432,host2:5433/console_database
CDK_KAFKASQL_DATABASE_URL: jdbc:postgresql://user:password@host1:5432,host2:5433/kafka_sql_database

For more information, check out the Multi-host configuration section in the Database configuration documentation.

Delegating authentication to an identity provider​

Console can now be configured to accept a JWT token from an external identity provider.
It allows you to directly use your identity provider for managing access to Console.
A common use case of this feature is to delegate authentication to your API gateway.

For the full configuration details, check out the documentation.

More Audit Log CloudEvents into Kafka​

We have made more events available for the Audit Log Publisher:

• Kafka.Subject.ChangeCompatibility
• Kafka.Topic.Browse
• Kafka.Topic.ProduceRecord
• Kafka.Topic.SqlQuery
• Kafka.Connector.Restart
• Kafka.Connector.Pause
• Kafka.Connector.Resume
• Kafka.Connector.RestartTask
• Kafka.Connector.AutoRestartActivate
• Kafka.Connector.AutoRestartStop

A full list of all the exported audit log event types is published on the Audit Log page.

Quality of Life improvements ✨​

• Alert lists in the resource pages have been updated to show the metric and condition, the alert state and a new column "Last Triggered"
• Chargeback data can now be exported into a CSV file to enable easier integration with existing organization cost management data.
• The User permission page provides a clearer distinction between inherited and user-specific permissions.
• Topic policy validation errors message are easier to read when using the CLI
• Added support for Array and Boolean types in Conduktor SQL
• Added Kafka Key column and other metadata in Conduktor SQL Topics (Full list)

Fixes 🔨​

• Fixed a pagination issue in the SQL Indexed Topics view
• Fixed several instances where the CLI would not report the expected state change (Updated vs. Not Changed) on apply

Gateway 3.5.0​

Release date: 2024-12-16

Breaking changes​

Breaking change: Local Users 💣​

From this release, we will now strictly enforce that the username and the token matches in requests made to the Gateway where local service accounts are used. This will help reduce inconsistencies and avoid unexpected behaviors. If they do not match, requests will fail to authenticate.

Breaking change: Default SNI Host Separator​

In this release we have changed the default value for the separator used in the SNI routing configuration from a period . to a dash -. This is in order to better allow the use of wild card certificates when certificates are in use.

The format of the SNI routing host names is now as below:

 <host_prefix><cluster_id><broker_id>-<advertised_host>

The previous behaviour of Gateway can be configured by simply adding this to your configuration:

GATEWAY_SNI_HOST_SEPARATOR=.

For more information on SNI routing, see its documentation.

Features ✨​

Use of In-memory KMS for Encryption​

Gateway has always supported the use of an in memory KMS for encryption in order to provide an easy-to-use setting for testing and developing your encryption config. This mode is not however meant for production use as the state of the KMS is lost when Gateway restarts, rendering any data encrypted with it unrecoverable.

Before this release, the in memory mode was the default setting and would be used as a fallback if no valid external KMS was detected in the encyrption setup.

From this release, you must now explicitly opt-in to the in-memory mode for encryption using the prefix:

in-memory-kms://

If this, or any other valid KMS identifier, is not present the encryption plugin will now fail. This change is a precaution to prevent accidental misconfigurations resulting in the use of in memory mode and subsequent data loss.

See the encryption configuration docs for more information.

License Expiry​

We have altered the behaviour of the Gateway when your license expires to provide a better experience. The behaviour is now as below:

• We have added new metric gateway.license.remaining_days which you can monitor to track the time left on your license
• If the Gateway is currently running, do not automatically exit on license expiry. Rather, Gateway will now log a warning every hour that your license is expired:

License has expired! You need to add a valid license to continue using Conduktor Gateway. Checkout our documentation if unsure how to set the license

• These warnings will start 1 week before expiry occurs as a notification, in the format:

License will expire in less than {N} day(s)! You need to renew your license to continue using Conduktor Gateway

• Finally, we now check your license earlier in the bootstrap sequence for Gateway, so it will fail fast with a clear message when your license is expired.

The key change here is that if your license does expire, Gateway will not exit automatically anymore. It will continue running, logging warnings. Should you restart the Gateway in this state, it will then fail to start up - but there is no automatic shutdown.

Quality of Life Improvements ✨​

• Support for Kafka Clients up to 3.9
• Improved compatibility and logging for dealing with kafka-client versions and version negotiations
• Added support for multiple authentication mechanisms against Vault (AppRole, LDAP, ...)
• Introduced a new configuration enableAuditLogOnError (default: true) which enhances the errors which are logged when encryption/decryption fails
• Improved error logging for expired tokens on authentication, to replace large stack traces with concise information
• Performance improvements for TLS handshakes, in particular to prevent repeated failed attempts overloading the gateway
• Several improvements to data quality and encryption config validation to provide better error reporting and feedback in the case of problems

General fixes 🔨​

• Fixed an issue in ACL handling which caused an error if no topics were passed for an offset fetch request (being the case where the caller wants to retrieve offsets for all topics).
• Fixed an issue in Virtual Clusters which in some cases meant the ACLs for the physical Kafka clusters where exposed in error.
• Fixed an issue in the regular expression application in the data quality and SQL plugins, where .* would not always match the entire value for a field
• Fix an issue when creating both a service account and a service account group through the cli to ensure the order of operations is always correct, preventing intermittent failures in this case.

Known issues​

• We are aware of an issue with kcat when the new environment variable GATEWAY_MIN_BROKERID is not aligned with the first BrokerId of your Kafka cluster
  • As a workaround, you can either define GATEWAY_MIN_BROKERID to your first Kafka BrokerId or use kcat with the -E flag

Console 1.29.2​

Release date: 2024-12-09

Fixes 🔨​

• Fixes a bug where SSO and LDAP sign ups were being rejected for users with upper-case letters in their email

Console 1.29.1​

Release date: 2024-11-28

Fixes 🔨​

• Fixed an issue where configuring Google OIDC without a scope was throwing an Exception.

Console 1.29.0​

Release date: 2024-11-25

• Breaking Changes 💣
  • Changes to Conduktor.io Labels
  • Local Users Password policy update
• Features ✨
  • Conduktor Chargeback
  • Console Homepage
  • Consumer Group pages overhaul
  • Self-Service Topic Catalog visibility
  • Self-Service New Topic Policy Allowed Keys
  • More Audit Log CloudEvents into Kafka
  • Expanded Terraform Provider
• Quality of Life improvements
• Fixes 🔨

Breaking Changes 💣​

Changes to Conduktor.io Labels​

We have moved the conduktor.io labels previously available on Connector and Topic resources to new locations.

We recognize this change breaches the API contract and have carefully considered its implications. We remain committed to minimizing breaking changes and will continue to do our best to ensure that such changes are rare and well-justified.

As we expand the number of Conduktor-related features, this separation reduces the risk of conflicts, simplifies resource management, and provides flexibility for future improvements:

• Labels used for sorting and filtering throughout the product
• Conduktor-specific annotations used to drive behaviors on the resources

Topic Resource

• metadata.labels.'conduktor.io/description' → metadata.description
• metadata.labels.'conduktor.io/description.editable' → metadata.descriptionIsEditable

Connector Resource

• metadata.labels.'conduktor.io/auto-restart-enabled' → metadata.autoRestart.enabled
• metadata.labels.'conduktor.io/auto-restart-frequency' → metadata.autoRestart.frequencySeconds

Their associated values have been automatically migrated under the new names.

Important Note for CLI Users​

Applying YAML files with old conduktor.io labels will fail in Conduktor Console 1.29. Be sure to update your YAML files to reflect the new labels.

Example error for outdated YAML:

$ conduktor apply -f topic.yaml
Could not apply resource Topic/click.event-stream.avro: Invalid value for: body (Couldn't decode key. at 'metadata.labels.conduktor.io/description')

Local Users Password policy update​

Passwords for console Local Users configured through YAML and environment variables must comply with a new password policy. This change enforces the following password requirements:

• At least 8 characters in length
• Includes at least 1 uppercase letter, 1 lowercase letter, 1 number, and 1 special symbol

Passwords set in existing installations that do not meet these requirements will prevent Console from starting, throwing a startup error in the logs like this:

2024-11-21T14:25:47,434Z [console] ERROR zio-slf4j-logger - zio.Config$Error$InvalidData: (Invalid data at admin: Password must contain at least 8 characters including 1 uppercase letter, 1 lowercase letter, 1 number and 1 special symbol)

Local Users previously created with the UI are not impacted.
Update the passwords in your YAML or environment variables to meet the new policy before upgrading.

Features ✨​

Conduktor Chargeback: Track and Allocate Costs & Resource Consumption​

Conduktor Chargeback allows organizations to track and allocate costs & usage associated with Kafka resources to different teams or departments based on their data consumption and processing, facilitating cost accountability and management.

Check the dedicated Quickstart to get started with Chargeback.

Console Homepage​

The cluster homepage have been redesigned to present you with the most useful information in one single view:

• The health of your Kafka Cluster with a few key metrics and graphs
• The state of Console Indexing modules for this Kafka Cluster
• Quick access to your most recently viewed resources

Consumer Group pages overhaul​

Consumer group details page is now organized in a way that helps understand the status of your Consumer Group more easily:

• Topics tab shows the Consumer Group info grouped by its subscribed Topics
• Members tab shows the Consumer Group info grouped by its active members

Both Topics and Members lists can be explored further down to individual member/topic-partition assignments.

On top of that graphs are now directly available in the resource page for Lag and Time Lag, as well as a dedicated tab to manage Alerts.

Self-Service Topic Catalog visibility​

You can now choose which Topics should be visible in the Topic Catalog by annotating their YAML.

---
apiVersion: kafka/v2
kind: Topic
metadata:
  cluster: shadow-it
  name: click.event-stream.avro
  catalogVisibility: PUBLIC # or PRIVATE
spec:
  ...

It is also possible to change the default Topic Catalog visibility of all Topics of an Application Instance directly
Check the associated documentation.

Self-Service New Topic Policy Allowed Keys​

We have added a new constraint AllowedKeys to our Self-Service Topic Policy that restricts the properties that can be configured on a Topic.

---
# Limits the Topic spec.configs to only have retention.ms and cleanup.policy keys
apiVersion: self-service/v1
kind: TopicPolicy
metadata:
  name: "generic-dev-topic"
spec:
  policies:
    spec.configs:
      constraint: AllowedKeys
      keys:
        - retention.ms
        - cleanup.policy

This works in conjunction with existing constraints and ensures your Application Teams will only define properties that are allowed by the Central Team.
Read more about our Topic Policy constraints.

More Audit Log CloudEvents into Kafka​

We have made more events available for the Audit Log Publisher:

• IAM.User.Logout
• IAM.User.Login
• Kafka.ConsumerGroup.Duplicate
• Kafka.ConsumerGroup.Delete
• Kafka.ConsumerGroup.Update ( when we reset the offset of the consumer group )

A full list of all the exported audit log event types is published on the Audit Log page.

Expanded Terraform Provider: Kafka Cluster, Schema Registry, Kafka Connect​

We've expanded the scope of our Terraform provider, you can now create additional resources: Kafka cluster with schema registry, and Kafka connect clusters using Terraform. With this version also comes some additional small fixes as requested by the community, see the dedicated provider releases page for the full list.

All examples are available in our provider repo such as the below snippet for a Confluent Kafka cluster and schema registry (with mTLS) definition.

resource "conduktor_kafka_cluster_v2" "confluent" {
  name = "confluent-cluster"
  labels = {
    "env" = "staging"
  }
  spec {
    display_name      = "Confluent Cluster"
    bootstrap_servers = "aaa-aaaa.us-west4.gcp.confluent.cloud:9092"
    properties = {
      "sasl.jaas.config"  = "org.apache.kafka.common.security.plain.PlainLoginModule required username='admin' password='admin-secret';"
      "security.protocol" = "SASL_PLAINTEXT"
      "sasl.mechanism"    = "PLAIN"
    }
    icon                         = "kafka"
    ignore_untrusted_certificate = false
    kafka_flavor = {
      type                     = "Confluent"
      key                      = "yourApiKey123456"
      secret                   = "yourApiSecret123456"
      confluent_environment_id = "env-12345"
      confluent_cluster_id     = "lkc-67890"
    }
    schema_registry = {
      type                         = "ConfluentLike"
      url                          = "https://bbb-bbbb.us-west4.gcp.confluent.cloud:8081"
      ignore_untrusted_certificate = false
      security = {
        type              = "SSLAuth"
        key               = <<EOT
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
EOT
        certificate_chain = <<EOT
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
EOT
      }
    }
  }
}

Quality of Life improvements​

• Improved the performance of the Automatic deserializer
• Improved the performance of the Schema Registry indexing process
• Added support for Google Cloud Identity group claims
• Added License expiry warning in the UI when there is less than 30 days left

Fixes 🔨​

• Fixed an issue where Custom Deserializers weren't working as expected
• Fixed an issue where the ManageClusters permission wasn't working as expected
• Fixed an issue that prevented creating a KafkaCluster and a Topic on that newly declared KafkaCluster in a single CLI apply command
• Fixed /health/readiness endpoint to return HTTP 503 when the Postgres DB is down
• Fixed an issue where the Message Count wasn't updated to 0 when emptying a topic
• Fixed an issue where the Pause/Resume button wasn't visible when a connector was in the Failed state
• Fixed an issue where the Topic creation failure reason wasn't shown in the UI
  • This helps understand why Topic Creation is rejected (useful for Gateway and Self-Service Topic Policies), and how to modify the topic create request to meet the policy requirements

Gateway 3.4.0​

Release date: 2024-11-15

Upcoming Breaking change: Local Users 💣​

Today, the token as the password for local Gateway service accounts contains all the necessary information. As a result, the SASL username is not used during the authentication phase.

In release 3.5.0, we will strictly enforce that the username and the token matches. This will help reduce inconsistencies and avoid unexpected behavior.

For this release 3.4.0, we'll only raise the following warning in the logs:

2024-08-27T18:15:29 [WARN] - Inconsistency detected for plain authentication. Username applicationA is not consistent with validated token created for application-A. SASL configuration should be changed accordingly.

Features ✨​

• Correct Offsets on Concentrated Topics

Correct Offsets on Concentrated Topics​

Concentrated Topics were reporting the offsets of the underlying backing topic. This caused Lag and Message Count metrics to be invalid.

Correct offsets can now be enabled per ConcentrationRule.

---
kind: ConcentrationRule
metadata:
  name: myapp-concentrated
spec:
  pattern: myapp-.*
  physicalTopics:
    delete: myapp-concentrated
  autoManaged: false
  offsetCorrectness: true

This feature is experimental and comes with a number of limitations that are important to understand beforehand.

General fixes 🔨​

• Fixed an issue impacting live consumption from concentrated topics within Console
• Fixed an issue with upserts in API V2 relating to service accounts (reporting updated when the status should be not changed)
• Fixed an issue related to Kafka 3.7 client support, ensuring topic id's for alias and concentrated topics are distinct from their underlying topics
• Fixed an issue whereby audit logs were not being captured during cluster switching
• Fixed an issue with SQL topics when parsing topic names containing "-"

Known issues​

• We are aware of an issue with kcat when the new environment variable GATEWAY_MIN_BROKERID is not aligned with the first BrokerId of your Kafka cluster
  • As a workaround, you can either define GATEWAY_MIN_BROKERID to your first Kafka BrokerId or use kcat with the -E flag

Console 1.28.0​

Release date: 2024-10-14

• Features ✨
  • Conduktor SQL
  • Monitoring improvements
  • New CLI/API resource Alert
  • Shareable Filters
  • Tags becomes Labels
  • Publish Audit Log CloudEvents into Kafka
  • Logging API
• Quality of Life improvements

Features ✨​

Conduktor SQL​

Index data from Kafka topics in a database to enable data to be queried from the UI, API or CLI using SQL.

This allows you to troubleshoot, sample, analyze, aggregate and join data through:

• Querying Kafka message data
• Querying Kafka metadata (such as the offset, partition and timestamp)

Read the dedicated guide on configuring SQL.

Query through the UI

Query through the API & CLI

CLI (upgrade to v0.3.1):

conduktor sql 'select * from "kafka-cluster-dev_customer_orders"' -n 2

API:

curl \
 --header "Authorization: $token" \
 --request POST 'localhost:8080/api/public/sql/v1/execute?maxLine=2' \
 --data 'select * from "kafka-cluster-dev_customer_orders"'

Important information regarding SQL

To use the feature there is a dependency on provisioning a new database. As a user, you have the choice of which topics you wish to index. Learn more about this and how to configure SQL using the dedicated guide.

We encourage you to use this feature in non-production environments and give us feedback.

Monitoring improvements​

We are migrating our Monitoring dashboards into their respective resource pages for a more integrated experience.

This migration will happen over the next few releases with our objective to remove the existing, generic Monitoring pages:

• Overview will be refactored into Home page
• Cluster Health dashboards and alerts will move under Brokers page
• Topic monitoring will be integrated with Topics page
• Apps monitoring will be integrated with Consumer Groups pages
• Alerts will be integrated as tabs in all the resource pages, similar to the recent changes for Kafka Connect

For this 1.28.0 release we are migrating the Topic monitoring and Cluster Health pages.

Topic Monitoring​

The 3 existing graphs have been moved to the Topic details. We have also added a new graph to track the number of records in the topic.

• Produce Rate and Consume Rate
• Disk Usage
• Records (new)

Cluster Health​

The charts and alerts are now available under the Brokers page with cleaner graphs.

• Produce Rate and Consume Rate
• Disk Usage
• Partitions Count
• Offline, Under Replicated and Under Min ISR Partitions

We have removed two metrics that were not always calculated correctly since the removal of the JMX integration back in release 1.15 (May 2023).

• Active Controller Count
• Unclean Leader Election

New CLI/API resource Alert​

Alerts can now be created via the API or CLI in addition to the UI.
See below for example config, and check the Alerts documentation for more details.

---
apiVersion: console/v2
kind: Alert
metadata:
  cluster: local-julien
  name: my-alert
spec:
  type: TopicAlert
  topicName: wikipedia-parsed-DLQ
  metric: MessageCount
  operator: GreaterThan
  threshold: 0

Starting today, we recommend you use the new alerts available under Brokers and Topics pages.

Shareable Filters​

Filters in the Topic Consume view are now shareable. This brings a number of benefits:

• Improved collaboration: Share pre-defined views to ensure users are looking at the same subset of data
• Time savings: Speed up troubleshooting and analysis with repeatable filters that share the same or similar criteria
• Consistency and accuracy: Standardized filters across teams and departments reduce the risk of errors or discrepancies that can occur when individuals manually create filters

After you've finished configuring filters on a topic, you now have an option to save the filter either as a Private or an Organization filter.

Anyone can then load Organization filters from the dedicated section.

Tags Become Labels​

With the introduction of the Self-service resource manifests, we brought customers a means to annotate all their resources with labels. Labels are more structured than the existing Conduktor tags, thereby allowing for more precise filtering capabilities, as can be seen in the Topic Catalog.

In this release, we'll perform an automatic migration from Tags to Labels.

Tags written with the naming convention <key>/<value> will automatically be added as similar labels:

• <key>: <value>

If there is a conflict such as; a topic containing tags with the same key, that already has the target label, or is not written with this naming convention, then they will be created with a tag- prefix as follows:

tag-<value>: true

Here's an example of how tags will be migrated into labels:

# Tags defined on topic:
- format/avro
- project/supplychain
- team/delivery
- color/blue
- color/red
- wikipedia
- non-prod

# Resulting topic labels after migration
labels:
  format: avro
  project: supplychain
  team: delivery
  tag-color/blue: true # Because conflict on "color"
  tag-color/red: true # Because conflict on "color"
  tag-wikipedia: true # Because wikipedia is not a key value pair
  tag-non-prod: true # Becuase non-prod is not a key value pair

The Topic list and Topic details page have been modified to use labels instead of tags.

We plan to bring this capability on all resources (Connectors, Service Accounts, Consumer Groups, ...) over the next few releases.
Let us know which resource you would like to see covered first.

Publish AuditLog CloudEvents into Kafka​

It is now possible to publish Console Audit Log events into a Kafka topic directly for any further use you may have for them, such as maintaining your own audit trail in other systems.

The exportable audit log events have more detail compared to the current UI events, providing additional information about the event that has taken place.

The events conform to the CloudEvents specification, a vendor-neutral format that follows the following structure:

{
    "specversion" : "1.0",
    "type" : "com.github.pull_request.opened",
    "source" : "https://github.com/cloudevents/spec/pull",
    "subject" : "123",
    "id" : "A234-1234-1234",
    "time" : "2018-04-05T17:31:00Z",
    "comexampleextension1" : "value",
    "comexampleothervalue" : 5,
    "datacontenttype" : "text/xml",
    "data" : "<much wow=\"xml\"/>"
}

An example Conduktor event would look like:

{
	"source": "//kafka/kafkacluster/production/topic/website-orders",
	"data": {
		"eventType": "Kafka.Topic.Create",
		// Additional event specific data...
		"metadata": {
			"name": "website-orders",
			"cluster": "production"
		}
		// Additional event specific metadata...
	},
	"datacontenttype": "application/json",
	"id": "ad85122c-0041-421e-b04b-6bc2ec901e08",
	"time": "2024-10-10T07:52:07.483140Z",
	"type": "AuditLogEventType(Kafka,Topic,Create)",
	"specversion": "1.0"
}

Specify the target Kafka cluster and topic using the environment variables CDK_AUDITLOGPUBLISHER_CLUSTER & CDK_AUDITLOGPUBLISHER_TOPICNAME and events will start being produced to the destination topic.

A full list of all the exported audit log event types is published on the Audit Log page.

Logging API​

Adjust the log level of Console without requiring a restart. We've added a new API endpoint to support targeted changes to log levels dynamically. Check the associated documentation for the full list of capabilities.

curl -X PUT 'http://localhost:8080/api/public/debug/v1/loggers/io.conduktor.authenticator/DEBUG' \
  -H "Authorization: Bearer $API_KEY"

Quality of Life improvements​

Console 1.27.0​

Release date: 2024-09-14

• Features ✨
  • Kafka Connect Configuration Wizard
  • Alerts for Kafka Connect
  • Self-service: Limited Ownership mode
  • Quality of Life improvements
• Fixes 🔨
• Deprecation Warning: Upcoming migration from Tags to Labels

Features ✨​

Kafka Connect Configuration Wizard​

We are very excited to introduce our Configuration Wizard for Kafka Connect which is taking full advantage of the Kafka Connect Validate API:

• Form is generated with structured configuration groups
• Much nicer error handling, attached to each individual field
• Embedded documentation that helps you understand which fields are required and what are their expected and default values
• Ability to toggle advanced configuration to visualize only the most important fields
• Ability to switch seamlessly between Form View and JSON View at any time.

Give it a try and let us know what you think!

Alerts for Kafka Connect​

On top of the Kafka Connect Graphs we shipped last release, we now have added the ability to create alerts on them.

Self-service: Limited Ownership mode​

To help organizations transition to Self-service more easily, we have added a new attribute on ApplicationInstance to let Platform Teams decide the level of autonomy to give to Application Teams.

• ApplicationInstance resources configured with ownershipMode: ALL, which is the default, delegates all permissions related to that resource to the Application Team
• ApplicationInstance resources configured with ownershipMode: LIMITED delegates only a subset of the available permissions to the Application Team

This is especially useful if you already have a centralized repository and existing workflow for Topic creation. You may want to provide Self-service capabilities while still forcing your Application Teams to go through your pipeline for Topic Creation, instead of Self-service.

• Read more about Limited Ownership mode
• Get Started with Self-service today!

Quality of Life improvements​

• Self-service: External Group Mapping is now available for ApplicationGroup
• The Login page now steers users towards their OIDC provider rather than basic auth when OIDC is enabled

Fixes 🔨​

• Fixed an issue on Consumer group reset offset with the ToDatetime strategy
• Fixed an issue with Console indexing that could occur when deleting and recreating subject
• Fixed a recent regression with default replication factor when creating a topic
• Fixed a recent regression with Broker feature "Similar config" calculation
• Fixed a UI issue when Application Instance was created without any resources
• Fixed several issues around Microsoft Teams Integration to support Teams Workflow webhooks (Step by step guide)
• Fixed Kafka Connect client to use HTTP Proxy JVM configuration
• Switching Kafka cluster from the Topic details page now redirects to the Topic List
• Console doesn't override the client.id property anymore

Deprecation Warning: Upcoming migration from Tags to Labels 💣​

With the introduction of the Self-service resource manifests, we brought customers a means to annotate all their resources with labels. Labels are more structured than the existing Conduktor tags, thereby allowing for more precise filtering capabilities, as can be seen in the Topic Catalog.

In an upcoming release, we'll perform an automatic migration from Tags to Labels.

Tags written with the naming convention <key>/<value> will automatically be added as similar labels:

• <key>: <value>

If there is a conflict such as; a topic containing tags with the same key, that already has the target label, or is not written with this naming convention, then they will be created as follows:

tag-<value>: true

Here's an example of how tags will be migrated into labels:

# Tags:
- format/avro
- project/supplychain
- team/delivery
- color/blue
- color/red
- wikipedia
- non-prod

# Result
labels:
  format: avro
  project: supplychain
  team: delivery
  tag-color/blue: true # Because conflict on "color"
  tag-color/red: true # Because conflict on "color"
  tag-wikipedia: true
  tag-non-prod: true

⚠️ Conduktor can help you rename tags through Customer Support
Between now and the migration, we can help you rename your tags for a smooth transition to labels.

Contact us as soon as possible if you would like support.

Gateway 3.3.0​

Release date: 2024-09-05

Upcoming Breaking change 💣​

Today, the token as the password for local Gateway service accounts contains all the necessary information. As a result, the SASL username is not used during the authentication phase.

In an upcoming release, we will strictly enforce that the username and the token matches. This will help reduce inconsistencies and avoid unexpected behaviors.

This breaking change is due for release 3.5.0.
For this release 3.3.0, and next product release 3.4.0, we'll only raise the following warning in the logs:

2024-08-27T18:15:29 [WARN] - Inconsistency detected for plain authentication. Username applicationA is not consistent with validated token created for application-A. SASL configuration should be changed accordingly.

Features ✨​

• New V2 APIs and CLI support
• Support for HTTPS APIs
• Better UX for ACLs and superUsers
• Encryption Enhancements and Support Clarification

New V2 APIs and CLI support​

We’re excited to introduce our new Gateway API, designed for seamless integration with our CLI. This update allows you to deploy Gateway resources using infrastructure-as-code with straightforward, clearly defined concepts:

• Interceptor
• GatewayServiceAccount
• GatewayGroup
• ConcentrationRule
• AliasTopic
• VirtualCluster

Check the CLI reference to get started, and the resources reference for more information on each concept.

---
apiVersion: gateway/v2
kind: GatewayGroup
metadata:
  name: groupB
spec:
  members:
    - name: user1
    - name: user2
---
apiVersion: gateway/v2
kind: Interceptor
metadata:
  name: enforce-partition-limit
  scope:
    group: groupB
spec:
  pluginClass: io.conduktor.gateway.interceptor.safeguard.CreateTopicPolicyPlugin
  priority: 100
  config:
    numPartition:
      action: BLOCK
      max: 9
      min: 9
    topic: .*

$ conduktor apply -f gateway.yml
GatewayGroup/groupB: Created
Interceptor/enforce-partition-limit: Created

$ conduktor delete GatewayGroup groupB
The group groupB is still used by the following interceptor(s): enforce-partition-limit

Note: API V1 is still available, but we recommend that new users and those with simple Gateway configurations begin using the V2 API as soon as possible. We will announce a deprecation plan in the coming weeks and notify you in advance of which Gateway version will be the last to support the V1 APIs.

Support for HTTPS APIs​

It is now possible to configure HTTPS and mTLS authentication on the Gateway HTTP APIs. Check the HTTP section of the Environment Variables page for more details.

Better UX for ACLs and superUsers​

To coincide with the clearly defined concepts established in API V2, we are making changes to ACLs management in Gateway.

• ACLs and Super Users on the Gateway (excluding Virtual Clusters) must be configured through Environment Variables.
• ACLs and Super Users on Virtual Clusters must now be driven explicitly through API/CLI.

Enable ACLs for Gateway (excl. Virtual Clusters)​

Configure both environment variables:

GATEWAY_ACL_ENABLED=true # default false
GATEWAY_SUPER_USERS=alice,bob

If GATEWAY_SUPER_USERS is not set, it will default to GATEWAY_ADMIN_API_USERS for backward compatibility.

Enable ACLs for Virtual Clusters​

Example configuration:

---
apiVersion: gateway/v2
kind: VirtualCluster
metadata:
  name: "mon-app-A"
spec:
  aclEnabled: "true" # defaults to false
  superUsers:
  - username1
  - username2

Encryption Enhancements and Support Clarification​

Field-Level Encryption: Preserving Message Format to Enhance Usability​

When applying field-level encryption prior to 3.3.0, the encryption plugin would convert the message to JSON, and re-apply the schema format when the message was read back through the decryption plugin.

In Gateway 3.3.0, we now preserve the schema format for Avro messages - meaning the same schema is used in the backing topic, and the data can be read directly from Kafka or without the decryption plugin at all.

Read more about this change to the default behaviour, and how to configure it.

Fields which cannot be encrypted in-place (effectively any non-string field) have their encrypted value placed in the headers, and the field itself is given a default masking value. The default values are clarified below:

Note that the same default values are now used across all relevant plugins when manipulating a non-string field - Data Masking, Partial Decrypt, and Encrypt on Fetch.

Attempt to apply encryption to a message more than once will now fail​

If any of the encryption headers are detected in a message when encryption is about to be applied, then the encryption operation will fail. This is because applying encryption twice (or more) is currently not reversible.

Deprecated support for Schema Based (tag) encryption with Protobuf​

Note this is no longer supported, and the Gateway will now throw an exception if the encryption plugin attempts to apply schema (tag) based processing to a Protobuf message.

Note that any data previously written in this mode can still be read back - as the decrypt does not use the schemas at all, rather it uses the message header to know what was encrypted.

General fixes 🔨​

• Large double values (where > Float Max) are now supported in field-level encryption for Avro and Protobuf
• Bytes and fixed fields now properly supported in field-level encryption for Avro
• Avro unions of two or more values (rather than just a value and a null) are now supported in field-level encryption for Avro
• Schema (tag) based encryption now checks and fails if its config is invalid
• It is not possible to encrypt the headers which the encryption plugin uses to manage its decryption process (as this would render the data unrecoverable)
• Improved log messages for Interceptors that reject actions, such as TopicPolicyPlugin
• Several improvements to the LargeMessage & LargeBatch Interceptors
• Fixed an issue where KCache topic initialization would fail silently and leave Gateway in an unusable state
• Added a new Environment Variable GATEWAY_MIN_BROKERID (default 0) that allows for determinist mapping of brokers and ports
• Improved network stability during Gateway scaling or Kafka topology changes
• Added support for overriding Kafka Producer properties used for Audit Log topic with GATEWAY_AUDIT_LOG_KAFKA_ environment variables
• Removed metric gateway.brokered_active_connections. This was equal to portCount with port mapping and always 1 in host mapping
• Changed metric gateway.request_expired tags: nodeHost/nodePort are replaced by nodeId/clusterId
• Fix default value for GATEWAY_UPSTREAM_THREAD config. The new intended default (number of CPU) previously was (2 x number of CPU).
• Fixed an issue with GATEWAY_ADVERTISED_SNI_PORT that wasn't working properly
• Add log level for io.confluent packages in default log configuration
• Add default value to non mandatory configruation value for min and max bytes in FetchPolicyInterceptor
• Fix an issue with Concentrated Topics creation with Redpanda

Known issues​

• We are aware of an issue with kcat when the new environment variable GATEWAY_MIN_BROKERID is not aligned with the first BrokerId of your Kafka cluster.
  • As a workaround, you can either define GATEWAY_MIN_BROKERID to your first Kafka BrokerId or use kcat with the -E flag
• It is not possible to add Service Accounts to GatewayGroups using API V2 unless they are previously declared as GatewayServiceAccount.
  • This is not a wanted behavior, especially for OAuth or Delegated Kafka Authentication where declaring a GatewayServiceAccount should not be needed. We'll address this issue in a follow-up release
  • API V1 (user-mapping) is not impacted
• If you perform a rolling upgrade to 3.3.0, Gateway nodes in earlier versions will show the following error in the logs: [ERROR] [KafkaCache:1007] - Failed to deserialize a value org.apache.avro.AvroTypeException: Expected field name not found: clusterId
  • This is fine and will not cause any further problems
• If you use Virtual Clusters and ACLs: After updating to 3.3.0, you must manage VirtualCluster's ACL and superUsers through V2 API.

Gateway 3.2.2​

Release date: 2024-08-28

Upcoming Breaking change 💣​

Today, the token as the password for local Gateway service accounts contains all the necessary information. As a result, the SASL username is not used during the authentication phase.
In an upcoming release, we will strictly enforce that the username and the token matches. This will help reduce inconsistencies and avoid unexpected behaviors.

This breaking change is due for release 3.5.0.
For this hotfix release 3.2.2, and next product releases 3.3.0 and 3.4.0s, we'll only raise the following warning in the logs:

2024-08-27T18:15:29 [WARN] - Inconsistency detected for plain authentication. Username applicationA is not consistent with validated token created for application-A. SASL configuration should be changed accordingly.

General fixes 🔨​

• Fixed a severe authentication issue with Gateway generated tokens that could lead to a different user being authenticated, effectively causing elevated privileges under certain conditions.
• Fixed an issue where GATEWAY_SNI_HOST_SEPARATOR couldn't be set to the value -
• Fixed an issue where GATEWAY_SNI_HOST_SEPARATOR wasn't properly taken in account
• Fixed an issue with GATEWAY_ADVERTISED_SNI_PORT that wasn't working properly

Console 1.26.0​

Release date: 2024-08-14

Features ✨​

• Manage Connectors using the CLI
• Self-service support for Connectors
• Enhanced UI & Alerts for Kafka Connect
• Quality of Life improvements
• Deprecation Warning: Upcoming migration from Tags to Labels

Manage Connectors using the CLI​

Continuing with the Infra-as-code approach, we are happy to introduce CLI support for Connectors, providing an efficient and automated way to manage your Kafka Connect resources.

---
apiVersion: kafka/v2
kind: Connector
metadata:
  connectCluster: kafka-connect
  name: click.my-connector
  labels:
    conduktor.io/auto-restart-enabled: true
    conduktor.io/auto-restart-frequency: 600
spec:
  config:
    connector.class: 'org.apache.kafka.connect.tools.MockSourceConnector'
    tasks.max: '1'
    topic: click.pageviews

Self-service support for Connectors​

Application Teams can now manage their Connectors with Self-service.
From now on, you can grant ownership to connectors on Self-service Application Instance.

---
apiVersion: self-service/v1
kind: ApplicationInstance
metadata:
  application: "clickstream-app"
  name: "clickstream-dev"
spec:
  cluster: "shadow-it"
  serviceAccount: "sa-clicko"
  resources:
    - type: CONNECTOR
      connectCluster: shadow-connect
      patternType: PREFIXED
      name: "click."

Enhanced UI & Graphs for Kafka Connect​

We have revisited the Kafka Connect UI in multiple ways to improve your experience:

• Connect Cluster selection screen with a preview of Connector status
• New graphs demonstrating the state of your Connector over time

Support for High Availability (HA) Console​

Multiple Console instances can now be deployed in parallel to achieve high availability.

This applies to the deployment of conduktor-console, while conduktor-console-cortex is currently limited to a single instance. The design ensures minimal impact on the cluster by assigning only one instance to handle the indexing of Kafka data used for performance monitoring.

Quality of Life improvements​

• The checkbox to skip TLS verification is now always visible
• The YAML for Topic object now allows number in spec.configs. Previously it was mandatory to quote all numbers.
• Self-service Topic Policies are now visible in the UI

Fixes 🔨​

• Topic Policies from Self-service are now properly enforced from the UI, as well as both the API and CLI
• Fix Kafka Connect Cluster list showing invalid number of running tasks

Deprecation Warning: Upcoming migration from Tags to Labels 💣​

With the introduction of the Self-service resource manifests, we brought customers a means to annotate all their resources with labels. Labels are more structured than the existing Conduktor tags, thereby allowing for more precise filtering capabilities, as can be seen in the Topic Catalog.

In an upcoming release, we'll perform an automatic migration from Tags to Labels.

Tags written with the naming convention <key>/<value> will automatically be added as similar labels:

• <key>: <value>

If there is a conflict such as; a topic containing tags with the same key, that already has the target label, or is not written with this naming convention, then they will be created as follows:

tag-<value>: true

Here's an example of how tags will be migrated into labels:

# Tags:
- format/avro
- project/supplychain
- team/delivery
- color/blue
- color/red
- wikipedia
- non-prod

# Result
labels:
  format: avro
  project: supplychain
  team: delivery
  tag-color/blue: true # Because conflict on "color"
  tag-color/red: true # Because conflict on "color"
  tag-wikipedia: true
  tag-non-prod: true

⚠️ Conduktor can help you rename tags through Customer Support
Between now and the migration, we can help you rename your tags for a smooth transition to labels.

Contact us as soon as possible if you would like support.

Gateway 3.2.1​

Release date: 2024-07-31

General fixes 🔨​

• Fixed an issue when either GATEWAY_ACL_ENABLED or GATEWAY_ACL_STORE_ENABLED was enabled resulting in ACLs being enforced in undesirable scenarios.

Gateway 3.2.0​

Release date: 2024-07-19

Breaking Changes 💣​

Two new backing topics are required for Gateway​

In the next release (3.3), we'll bring a new API as well as support in the Conduktor CLI to manage Gateway concepts using infra-as-code approach.

In preparation for this upcoming release, we are replacing some weakly-defined concepts in favor of strongly-defined concepts. The following are now clearly captured in the topics mentioned below:

• Virtual Clusters that existed only through creation of UserMappings or Interceptors targeting
• GatewayGroups that existed only through UserMappings

As a result, 2 new topics will now be created once you upgrade to Gateway 3.2:

• _conduktor_gateway_vclusters
• _conduktor_gateway_groups

If you are happy with the default names, you have nothing to do. If you want to control the name of those topics, use the 2 new environment variables:

• GATEWAY_VCLUSTERS_TOPIC
• GATEWAY_GROUPS_TOPIC

Check the associated Documentation for more information.

Changes to ACL support on Gateway​

With Gateway 3.1 we removed our dedicated ACL interceptor in favor of a new environment variable GATEWAY_ACL_STORE_ENABLED. This variable was enabling ACLs in all scenarios, whether you used Virtual Clusters or not.

Changes for Gateway 3.2​

With Gateway 3.2, we are adding a new environment variable GATEWAY_ACL_ENABLED and modifying the behavior of the existing variable GATEWAY_ACL_STORE_ENABLED.

From now on, the variables works as follow:

Preview for Gateway 3.3​

In the next release, we will enhance ACLs to restore and expand the full set of features available before version 3.1. This will be achieved through the introduction of a CLI and APIs, making concepts like VirtualCluster first-class citizens.

Enable ACLs for Gateway (excl. Virtual Clusters)​

Configure both environment variables:

GATEWAY_ACL_ENABLED=true
GATEWAY_SUPER_USERS=alice,bob

Enable ACLs for Virtual Clusters​

---
apiVersion: gateway/v2
kind: VirtualCluster
metadata:
  name: "mon-app-A"
spec:
  aclEnabled: true # defaults to false
  superUsers:
  - username1
  - username2

This will effectively render GATEWAY_ACL_STORE_ENABLED obsolete.

General fixes 🔨​

• Fixed an issue with Field-level Avro encryption/decryption relating to numeric fields:
  • When using partial decryption with Avro schema registry, any numeric values (int, long, float, double) that are not being decrypted will instead be masked with the minimum (most negative) value for the numeric type
  • This is to ensure the field is compliant with the original type in the Avro schema
• Fixed an issue with the ClientIdRequired Policy that wasn't properly overriding the ClientId
• Fixed an issue to ensure all active connections are closed, and clients transition quicker to the new cluster during cluster switching

Console 1.25.1​

Release date: 2024-07-23

Breaking Changes 💣​

New docker image name​

We have renamed the Console docker image to conduktor/conduktor-console to clarify our product naming.
Please modify your installation to reflect this change as we will now stop publishing a conduktor/conduktor-platform image.

docker pull conduktor/conduktor-console:1.25.1

Features ✨​

• Conduktor Console IaC Compatible
  • Manage Cluster Connections
  • Short lived token generation on startup
  • Admin and Application Tokens
• Shareable Message Page
• Large Messages Support
• Topic Catalog Details Page
• Audit Last Activity of Users
• Quality of Life improvements

Conduktor Console IaC Compatible​

Console is now able to be fully deployed through an IaC approach with the following additions to Console 1.25 and CLI 0.2.7.

Manage Cluster Connections​

Manage your Console resource lifecycle with the addition of the KafkaCluster, KafkaConnectCluster and KsqlDBCluster objects to our IaC approach using the Conduktor CLI.

Checkout the example below and find the full definition at Console Resources Reference documentation.

---
apiVersion: console/v2
kind: KafkaCluster
metadata:
  name: cloud-kafka
spec:
  displayName: "Cloud Kafka"
  icon: "kafka"
  color: "#000000"
  bootstrapServers: "localhost:9092"
  properties:
    sasl.jaas.config: org.apache.kafka.common.security.plain.PlainLoginModule required username="admin" password="admin-secret";
    security.protocol: SASL_SSL
    sasl.mechanism: PLAIN
  schemaRegistry:
    url: http://localhost:8080
    security:
      type: BasicAuth
      username: some_user
      password: some_user

Short lived token generation on startup​

When spinning up Console, a token is needed to access the API. Previoulsy this had to be done in the UI which would not allow full IaC. Now, we have the conduktor login command which leverages the admin credentials to generate an API token, and allow the rest of the commands you may need to startup. This is expanded upon in the docs.

Admin and Application Tokens​

In addition to the startup token, you can now generate tokens for the appropriate scope, for admin and application level tokens. The docs will walk you through this.

Shareable Message Page​

Individual messages can now be accessed from a unique URL! Now you can link directly to a specific Kafka message for review or investigation, be that for sharing with a teammate, or commenting on a Jira ticket.

From within the Consume page, select a message and use the 'Share' button to navigate to the standalone page. The standalone message page shows the key, value, metadata and headers in a single view. Switch between the JSON view or table view, and utilize jq for additional filtering of the value.

Large Messages Support​

We have put a limit on the message sizes that are sent to the browser in the Consume page (100Kb). From now on, when a message is larger than this size, we'll provide you with a link to access the individual message - this mitigates performance issues and still provides a path for troubleshooting, and sharing, large messages.

Topic Catalog Details Page​

Expose contextual documentation about your Kafka Topics that exist in your organization with the Topic Details page. This helps democratize data to enhance its understanding and usage, and facilitate collaboration through a shared knowledge base.

You can choose to open or lock editing of descriptions within the UI using specific annotations. Check the Topic Resource documentation for more information.

Audit Last Activity of Users​

You can now audit the last activity date of users in Console.

From within the Settings > Users page, you will see a new column 'Last login'. Note that the user login event is also captured in the Audit Log.

Quality of Life improvements​

• Introduced an intermediate screen for Kafka Connect, allowing you to segment Connectors by each Connect cluster
• Within a Connect cluster, introduced an icon for each connector that clarifies if auto-restart is enabled
• Topic Catalog Search is now case-insensitive
• Improved error message when trying to delete an ApplicationInstance that is referenced elsewhere

Change in ApplicationInstance Resource Type from GROUP to CONSUMER_GROUP​

We have renamed the resource type in ApplicationInstance from GROUP to CONSUMER_GROUP. This change is intended to prevent confusion with the newly introduced resources ApplicationGroup and Group.

---
kind: ApplicationInstance
spec:
  resources:
    - type: CONSUMER_GROUP        # Previously: GROUP
      name: "click."
      patternType: PREFIXED

  • ApplicationGroup
  • Topic Catalog
• Manage Groups and Users using the CLI
• Topic list columns Produce Rate and Last Activity
• Active Data Policies in Topic Consume page
• Quality of Life improvements
• Fixes 🔨

Self-service​

There's a host of new functionality available providing a truly powerful self-service release. This comes from the addition of two new resources: Subject and ApplicationGroup

Application Teams can now manage their Subject resource lifecycle through IaC with the addition of the Subject object.

A new concept, ApplicationGroup lets Application Teams fully organize themselves within their Application scope to restrict who can do what over their resources within Console UI. It's a form of delegated RBAC.

Checkout the definitions below and find the full list of resource definitions via the Resource Reference documentation.

Subject​

This creates a Subject in the Schema Registry.

---
apiVersion: v1
kind: Subject
metadata:
  cluster: shadow-it
  name: myPrefix.topic-value
spec:
  schemaFile: schemas/topic.avsc # relative to conduktor CLI execution context
  format: AVRO
  compatibility: FORWARD_TRANSITIVE

ApplicationGroup​

Create an Application Group to directly reflect how your Application operates. You can create as many Application Groups as required to restrict or represent the different teams that use Console on your Application, e.g.:

• Support Team with only Read Access in Production
• DevOps Team with extended access across all environments
• Developers with higher permissions in Dev

# Permissions granted to Console users in the Application
---
apiVersion: v1
kind: ApplicationGroup
metadata:
  application: "clickstream-app"
  name: "clickstream-support"
spec:
  displayName: Support Clickstream
  description: |
    Members of the Support Group are allowed:
      Read access on all the resources
      Can reset offsets
  permissions:
    - appInstance: clickstream-app-dev
      resourceType: TOPIC
      patternType: "LITERAL"
      name: "*" # All owned & subscribed topics
      permissions: ["topicViewConfig", "topicConsume"]
    - appInstance: clickstream-app-dev
      resourceType: GROUP
      patternType: "LITERAL"
      name: "*" # All owned consumer groups
      permissions: ["consumerGroupReset", "consumerGroupView"]
  members:
    - alice@company.org
    - bob@company.org

Topic Catalog​

We're expanding on the Topic Catalog, to help teams discover Kafka Topics within your organization. You can now filter on all the topics based on user-defined, business metadata. Looking to request access to another applications resources? You can now generate the required ApplicationInstancePermission snippet that grants the necessary access to Topics belonging to another Application.

Manage Groups and Users using the CLI​

Manage your Console Group and Permissions lifecycle through IaC with the addition of the Group and User objects.
Checkout the example below and find the full definition via the Resource Reference documentation.

---
apiVersion: v2
kind: Group
metadata:
  name: developers-a
spec:
  displayName: "Developers Team A"
  description: "Members of the Team A - Developers"
  externalGroups: 
    - "LDAP-GRP-A-DEV"
  members:
    - member1@company.org
    - member2@company.org
  permissions:
    - resourceType: TOPIC
      cluster: shadow-it
      patternType: PREFIXED
      name: toto-
      permissions:
        - topicViewConfig
        - topicConsume
        - topicProduce

Topic list columns Produce Rate and Last Activity​

We added two new columns to the Topic List to help you troubleshoot and understand Kafka better: Produce Rate & Last Activity.

Values are computed once per Indexing (i.e. every 30s);

• Produce Rate is calculated from the two most recent offset values provided by our indexer.

• Last Activity is set to Datetime.now() if the latest offsets have changed since the last Indexing

Active Data Policies in Topic Consume page​

When exploring topics, fields masked by active Data Policies are now displayed in a different color, while the policy name is also now visible on hover.

Quality of Life improvements​

Topic pages

• You can now see all subjects associated to the Schema Id of the current message from the Message Viewer panel
• Added message Compression Type metadata in the Message Viewer panel
• Added buttons to navigate to previous and next message in the Message Viewer panel. Also works with the arrow keys

Self-service​

There's a host of new functionality available providing our first truly powerful self-service release. This comes from the addition of two new resources (Topic, TopicPolicy), application tokens, a topic catalog and service account synchronization.

Application Teams can now manage their Topic resource lifecycle through IaC with the addition of the Topic object, and they can do this safely with Platform Teams putting in place a Topic Policy to restrict expensive configurations and enforce naming standards.

Checkout the definitions below and find the full list of resource definitions via the Resource Reference documentation.

Topic​

This creates a Topic in the defined cluster.

---
apiVersion: v2
kind: Topic
metadata:
  cluster: shadow-it
  name: click.event-stream.avro
spec:
  replicationFactor: 3
  partitions: 3
  configs:
    min.insync.replicas: '2'
    cleanup.policy: delete
    retention.ms: '60000'

TopicPolicy​

TopicPolicy lets Platform Team define governance rules to restrict Application Teams to create Topics with misconfigurations. This is also useful to enforce naming convention or metadata annotation by Application Teams.

---
apiVersion: "v1"
kind: "TopicPolicy"
metadata:
  name: "click-naming-rule"
spec:
  policies:
    metadata.name:
      constraint: Match
      pattern: ^click\.(?<event>[a-z0-9-]+)\.(avro|json)$
    spec.replication.factor:
      constraint: OneOf
      values: ["3"]
    spec.configs.retention.ms:
      constraint: Range
      max: 604800000  # 7d 
      min: 3600000    # 1h

Topic Catalog​

We've introduced the Topic Catalog, to help teams discover Kafka Topics within your organization. Quickly get visbility on ownership and business metadata on your choice for topics.

Add topics to applications to see them appear within the catalog across all your clusters, searchable by name and labels.

Application API Keys​

Generate ApplicationInstance API Keys to create any ApplicationInstance scoped resources. Only ApplicationInstancePermission and Topic are supported at the moment.

Use this Key with the CLI to use it manually or within CI/CD pipelines.

In addition, Service Account's ACLs are now synchronized with the permissions from ApplicationInstance and ApplicationInstancePermission resources.

Topic as a Service becomes Self-service​

Self-service is a replacement for Topic as a Service. It is more centered towards a GitOps way of working, though we have performed a migration for existing TaaS applications to ensure a seamless transition to the new model:

• Applications + Environments are migrated to Application and ApplicationInstance
• Cross Application accesses are migrated to ApplicationInstancePermission
• The Application list becomes Application Catalog
• At the moment, we decided that we should control everything from the CLI only. The UI will remain Read-Only for now, but the intention is to bring back UI-driven operations in a future release.

Read More about Self-service

To start using Self-service, you must download our Conduktor CLI which lets you deploy resource files in Console.

Conduktor CLI​

Console now has a CLI! Get Started with it today.

For now, we only support the following resources:

• Application
• ApplicationInstance
• ApplicationInstancePermission

Our objective is to let Application Teams and Central Teams manage both Console resources (Clusters, Groups, Permission, Self-service resources, DataPolicies, Alerts, ...) and Kafka resources (Topics, Subjects, Connectors, ...) using a common definition mechanism.

More to come, automate everything!

This implies you might have a duplicate Connect instance if you use a YAML file with an ID for your Connect cluster. Check the Environment Variables page for more details
• Added new configurations to tune indexing batching and parallelization.s
• Fixed an issue with Azure PostgreSQL preventing the Schema Registry page from displaying properly

Gateway 3.0.0​

Release date: 2024-03-20

This major release of the Gateway brings functionality around targeting your interceptors more specifically, adding additional data quality & filtering tools and a host of rework under the hood for improved reliability & robustness. This can be seen in the form of reworked authorization to more closely align with what you're used to in the existing Kafka world and a more intuitive experience when working with the enhanced functionality Conduktor brings in concentrated and alias topics.

Features​

Interceptor Targeting​

Interceptors can now target more specifically than the previous scopes of vcluster and username. They can now be targeted at the global, vcluster, group(new), or service account level. Below are some areas and examples where targeting interceptors brings great power in their flexibility.

Apply interceptors on groups, across several service accounts, without duplicating the interceptor​

On a given Kafka cluster, each application may have different policy requirements.

Applications could be part of an organization's domain (finance, HR, Sales, etc.) or grouped by another dimension, such as data sensitivity. Platform teams will want to manage rules that apply to multiple applications at a "group" level.

Override behavior at a more specific service account, or group level​

Rather than apply interceptors across a wider domain, they may want to zoom in and target a specific application to override the wider defaults.

Examples:

A project from a domain is more advanced and doesn't need the safeguarding protections applied to the wider group.

• They know how to size topics correctly and are allowed a higher limit on partitions for topic creation, than the rest of the group
• Everyone is required to have compression enforced by default, but for this specific team they are allowed to remove it to meet a low latency requirement

Data quality validation rules across fields, using CEL​

Validate data across fields using Common Expression Language. Before we could define rules for fields within a schema, a great way to ensure data quality catching the data before it hits the cluster. Now, we can relate fields to each other. We can bring together data quality and business rules within our schema.

An example for age and email checks in our schema:

{
  "fields": [
    {
      "name": "age",
      "type": "int",
      "minimum": 18
    },
    {
      "name": "email",
      "type": "string",
      "format": "email"
    }
  ],
  "metatadata": {
    "rules": [
      {
        "name": "old people",
        "expression": "age >= 40 && email.endsWith('yahoo.com')",
        "message": "yahoo.com emails are allow only for people older that 40"
      }
    ]
  }
}

Filter messages on topics, using CEL​

Topic filtering can now be done with a simple plugin rather than building yet another pipeline. Effortlessly tailor message filtering rules to your use cases, ensuring only the most relevant data reaches your consumers.

Similar to how we allow you to filter data using SQL, you can now use CEL. By leveraging CEL expressions, you gain the flexibility to filter messages based on various attributes such as record key, value, partition, timestamp, header, and offset, offering unparalleled control over your data consumption.

Suppose you want to filter messages where the timestamp is greater than a certain threshold and the record key matches a specific pattern. With the enhanced CEL topic filtering feature, achieving this becomes straightforward as posting a plugin with the config:

{
  "virtualTopic": "your-topic-name",
  "expression": "record.timestamp > 1616400000000 && record.key.startsWith('prefix_')"
}

Topic multiplexing enhancements​

Several enhancements have been made when working with concentrated topics for topic multiplexing. Concentration can now be achieved on the default vcluster, passthrough. UX has been adjusted from using patterns only in favor of concentration rules, which have a dedicated part of the API.

Alias topic enhancements​

Alias topics (dedicated to referencing another topic within your cluster, see the docs for more) have been reworked for a more intuitive experience. Alias topics no longer replace the physical topic during interactions, but are seen as another topic. This will help in use cases related to migration, when applications use different topic names, and when exposing more topics within vclusters.

Default vcluster rework​

The default vcluster, passthrough, now has users associated with it by default rather than being rejected. This behavior can be reverted through configuration; see the docs for more.

General fixes 🔨​

• Fixed an issue that was prefixing consumer group names with Gateway in certain virtual clusters
• Simplified the security protocol experience, dropping the need for GATEWAY_MODE(s) to be defined, instead using Kafka standard security protocols or DELEGATED security protocols. Refer to the docs for more
• Less noisy metrics
• Configuration topics are now prefixed with the clusterID to prevent unintentional
• The PUT HTTP verb is now supported throughout the API
• ARM build is now available for the distro and distro-less images, to provide more flexibility to your deployment machine choices

Console 1.21.1​

Release date: 2024-03-05

New docker image name​

To clarify our product naming we have renamed the Console docker image to conduktor/conduktor-console.

We will publish newer versions using both names for the next three releases only. Please modify your installation to reflect this change in advance of us deprecating the name conduktor-platform.

docker pull conduktor/conduktor-console:1.21.0

Features ✨​

• ksqlDB
• Metrics available via Prometheus
• Smart tables for Connect and Schema Registry
• Add Local Users from the UI
• Fixes

ksqlDB​

Say hello to seamless integration with ksqlDB for you and your team on Conduktor Console.
Grant permission to whom can access the interface to create queries, setup new connections and visualise the existing connections.

Now you can:

• Browse ksqlDB clusters that are connected to Console
• Visualize all the currently running queries as well as write your own queries or executes statements
• Visualize and act on the running Streams (resulting from CREATE STREAM statements) with the Streams tab
• Visualize and act on the running Streams (resulting from CREATE TABLE statements) with the Tables tab
• Show all the Persistent and Push queries currently running on the ksqlDB Cluster with the Queries tab
• Execute Pull and Pull Queries (SELECT) and Statements (CREATE, DESCRIBE, DROP, ...) with the Editor tab

More info about kSQL is available on their website.

For more information checkout the docs.

Subscribe to metrics via the Prometheus endpoint​

Gain deeper insights into your system's performance with metrics now readily available via the Prometheus endpoint. No need for yet another system to monitor, seamlessly integrate metrics directly into your external log system in the Prometheus format, allowing for effortless monitoring and optimization of Conduktor within your systems.

You can monitor metrics such as under replicated partitions, total & failed connector tasks and consumer group lags. For the full list of available metrics checkout the docs.

Smart tables for Kafka Connect and Schema Registry subjects​

Get the answers you need quicker with the new tables. Sort by what matters, be that subject name, version count, latest version and more! For Connect there's all the usual suspects: source/sink, topics, the connect cluster and importantly the state (e.g. Failed, Paused). Quickly find which connectors are failing with just one click.

Choose what columns to hide the noise. Filter on name, tags and other resource metatdata such as consumer group state.

Add Local Users from the UI​

Don't have SSO ? Now you can add Users directly from the Users & Groups page in Settings, instead of modifying the config file and restarting the Console.

Fixes 🔨​

• Added support for complex union-type avro messages in Console Producer
• Fixed a blank screen issue after login due to case-sensitivity bug with email address
• Fixed an issue where Message Reprocessing didn't work after refreshing the page
• Resolved an issue with MSK role assumption
• Fixed an issue with custom certificates for Schema Registry and Kafka Connect

UI Navigation Overhaul​

Transition more seamlessly between different areas of the Console with a new UI experience. Everything Kafka related can now be accessed from the side bar, making it easier to navigate directly to your desired location in even fewer clicks. This change consolidates the app experience and puts all of Conduktor's power at your fingertips!

---

Sort, Filter and Customize the Topic List & Consumer Group List​

It probably looks underwhelming on the surface, but trust us... it's big! 🚀

On the menu:

• Sortable columns (size, messages count, partitions, ...). You can now sort by what matters to you. For example, the highest message count or the most partitions.
• Instant results. We are not querying Kafka, so it's fast whether you have 10 topics or 1,000 topics.
• Choose the columns that matter and hide away the ones that don't.
• Filters on name, tags and other resource metadata such as consumer group state.

Other features and improvements​

When adding a filter to search in a specific field, the input is now an autocomplete text field instead of a dropdown list. It's now even quicker to create your own filters on the fly!

The Table view quick filter buttons now generates Simple Filters instead of advanced JS filters.

Say goodbye to internal UUIDs! URLs are now taking advantage of the user-defined technical id making sharable links all the more readable with colleagues.

Fixes 🔨​

• Hide Provider tab secrets on the Cluster Configuration page
• Adding an ACL in the Service Account page now adds the entry at the bottom of the list
• Modifying filters in Topic Consume page or Topic/ConsumerGroup Lists page now resets the view to page 1
• Removed labels (member_host, consumer_id and client_id) in monitoring metrics to limit data points duplication generated during consumer group re-balances. This could cause ingestion limit issues in Cortex for large deployments
• Fixed an issue where wrong data could be displayed when recreating a different cluster with the same technical id
• Added support for Console certificates when making calls to Gateway API
• Optimized Memory configuration -XX:+UseContainerSupport -XX:MaxRAMPercentage=70 -XX:MaxDirectMemorySize=100m
• And many more UI fixes throughout the product

Console 1.19.2​

Release date: 2023-11-23

• Fixed an issue with the Reset Offset Preview in the Consumer Groups details showing incorrect target offsets
• Fixed an issue with Service Account page where prefix ACLs were saved incorrectly (prefix-* instead of prefix-)
• Fixed an issue with Service Account page where forcing an operation to "Not Set" caused an error on save
• Fixed an issue with Audit Log after upgrading from 1.18 and previous versions
• Fixed a UI issue where ACLs could not be deleted by non-Admin group members
• Fixed multiple UI issues with Topic As a Service
• Added new configurations for better OIDC support (allow-unsigned-id-tokens and preferred-jws-algorithm)

Console 1.19.1​

Release date: 2023-11-09

Fixes 🔨​

• Massive improvement over the indexing time of your cluster. This is especially notable if you have a large number of consumer groups (> 200) on your Kafka cluster.
• Fixed an issue where Gateway Interceptors could be created/deleted by all users instead of Admin group members.
• Fixed an issue where Monitoring didn't work for non-Admin group members.
• Fixed an issue that occurred when deleting a user from Console.

---

Consume live messages​

You can now consume live messages from within the topic consume screen. Simply set the limit filter to None and you'll see new records flowing as they are being produced. Streaming data is beautiful, isn't it? 😉

---

Consume messages infinitely​

We have finally said goodbye to the 5000 records limitation! If you wish to consume 100k records, 10M records, or even an entire topic, it's now possible! Note that for performance reasons, your browser will only store the most recent 5000 records available for browsing, or for use via the export feature.

Warning, we're not responsible for the sudden spike in your billing for Bytes-Out.

---

Consume between dates (and obtain count statistics)​

If you want to know how many messages were produced between two datetimes, you know have a new limit option dedicated for this. Simply apply the following filters:

• Show from: {datetime}
• Limit: {datetime}

It works particularly well in conjunction with filters, whereby you can now count how many messages matched your filters and how many total messages were produced between those dates.

Note that in the example below, 190 records matches the filter conditions, out of the total 10,522 consumed.

---

Provider Integrations within Conduktor Console​

Connect with your Kafka Provider to manage their benefits directly in Conduktor Console. With this first iteration, we bring features to Console that are only available with the provider's APIs.

---

Conduktor Gateway Integration​

You can now connect our other product artefact, Conduktor Gateway, to the Conduktor Console. This enables you to configure interceptors on Gateway virtual clusters through a dedicated set of pages accessible via the Gateway Interceptors tab.

Note that you will need to be connected to a Gateway cluster to utilize this feature. You can explore interactive demos below:

• Configure end-to-end encryption on Kafka topics
• Enforcing governance on configurations when creating topics

---

Aiven Cloud Integration​

We now support the following resources from Aiven Cloud:

• Manage Service Accounts
• Manage ACLs

To manage Aiven resources, navigate to the Service Accounts screen when connected to an Aiven Kafka cluster.

---

Confluent Cloud Integration​

We now support the following resources from Confluent Cloud:

• Manage Service Accounts & ACLs
• Manage API Keys

To manage Confluent Cloud resources, navigate to the Service Accounts screen when connected to a Confluent Cloud Kafka cluster.

---

YAML and Environment Variables for Clusters​

Kafka Clusters, Schema Registry and Kafka Connects configurations are now properly synced when configured from Yaml and Environment Variables (ie. GitOps way)

clusters:
  - id: ccloud
    name: Confluent Cloud ABCD
    bootstrapServers: lkc-abcd.europe-west1.gcp.confluent.cloud:9092
    properties: |
      security.protocol=SASL_SSL
      sasl.mechanism=PLAIN
      sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required \
        username='<CLUSTER-API-KEY>' \ 
        password='<CLUSTER-API-PASSWORD>';
    kafkaflavor: # Optional, for Service Accounts & Api Key support
      type: Confluent
      key: "<GLOBAL-API-KEY>"
      secret: "<GLOBAL-API-SECRET>"
      confluentEnvironmentId: "env-abcd"
      confluentClusterId: "lkc-abcd"
    schemaRegistry:
      url: http://abcd.europe-west1.gcp.confluent.cloud/
      security:
        username: <REGISTRY-API-KEY>
        password: <REGISTRY-API-PASSWORD>
    kafkaConnects:
      - id: kafka-connect-1
        name: Connect 1
        url: http://kafka-connect-1:8083/
        security:
          username: username
          password: password
    

Previously, configuring clusters using Yaml or Environment Variables was acting as INSERT-only (ie. Not Gitops).

We still recommend the use of Console API to maintain your Cluster configurations

---

Better memory configuration​

RUN_MODE is gone!
We now rely on container CGroups limits and use up to 80% of container memory limit for JVM max heap size. Our settings are the following

-XX:+UseContainerSupport -XX:MaxRAMPercentage=80

What does it mean for you?
You now only need to care about the limits that you set to your container.
Read this article to understand what this is about.

---

Fixes 🔨​

• Optimized the AdminClient instances usage across Console, by reusing a shared instance as much as possible. This will hugely decrease the number of AdminClient authentications.
• Fixed an issue on Consumer Group details where unassigned partitions were showing as part of an active member
• Fixed an issue on Consumer Group Page where pagination and search didn't work together properly

• Added support for Cortex configuration overrides (mounting a file in /opt/override-configs/cortex.yaml)

Console 1.18.4​

Release date: 2023-10-18

Fixes 🔨​

• Fixed an issue that prevented Console to function properly with PgBouncer
• Fixed an issue where properties (default.api.timeout.ms & request.timeout.ms) were mistakenly overridden, leading to possible timeouts on large Kafka Clusters
• (1.18.3) Fixed a performance issue on the Topic List page, leading to possible timeouts on large Kafka Clusters

Console 1.18.2​

Release date: 2023-10-04

Fixes 🔨​

• Fixed an issue on the Consumer Group List page that caused the page to timeout with a high number of consumer groups.

Console 1.18.1​

Release date: 2023-09-26

Fixes 🔨​

• Increased timeout from 30s to 5m when indexing snapshots (used for caching list pages) of Kafka clusters
• Fixed a DB issue that prevented authentication to succeed when the generated token was longer than 255 characters
• Fixed an issue with cortex (conduktor/conduktor-platform-cortex) when console (conduktor/conduktor-platform) is configured with HTTPS
• Fixed an issue where LDAP users could not see or configure Alerts under certain circumstances

Console 1.18.0​

Release date: 2023-09-11

This release contains several breaking changes so please read the entire release note prior to installation.

Important changes to our internal architecture ❗​

We are cleaning up our Docker image to bring you a simpler, lighter, and generally more operable product.

• We have extracted the 'Storage & Alerting' aspect of the Monitoring Solution from the base Console image and moved it to a dependency image
  • If you didn't use Monitoring, no further action is required from your part
• We have removed the embedded Postgres Database from the Docker image
• We have removed Testing from the base image
• We have rewritten our authentication module. If you have any issue with authentication using LDAP or OIDC with this new release Contact Conduktor Support

Features ✨​

User Friendly Filters​

We have completely revamped our filtering UX in the Consume page to be more aligned with your day-to-day use cases. Now you can search your topics by combining any of the following filtering mechanisms.

Simple Filters​

Search for any text in your messages either in your Key, or Value, using basic operators like "equals" or "contains".

Field Filters​

If your message is JSON, Avro or Protobuf, find values from specific fields. Operators can match the selected field type.

Advanced Filters​

For when you require more complex rules, Advanced Filters will give you the full power of JS to construct your own custom filters.

New Design for Service Accounts & Kafka ACLs​

We've overhauled Kafka ACLs and service account management. Visualize, create and edit your Kafka ACLs right within the UI with a simple but powerful design. Pair this with our market leading RBAC capability to empower only those that need it .

Reduced Memory Footprint​

As a result of our improvements to our internal architecture, we are happy to share that we have lowered our hardware requirements.
If you are currently deployed in prod using RUN_MODE=nano or RUN_MODE=small, please update the RUN_MODE based on your available memory after looking at our documentation.
If you are using higher RUN_MODE, you can free up some memory and save on infrastructure costs.
Visit our System Requirements page to see the changes.

Fixes 🔨​

• Fixed a UI issue where Add Partitions wasn't possible when using Firefox
• Fixed some UI issues with Kafka Connect and RBAC
• Added the "Last Indexed Date" info in the Consumer Groups List, to inform the user about the snapshot age
• Fixed an issue where Consumer Groups Details was populated from the snapshot, instead of AdminClient calls
• Fixed an issue where the Delete Consumer Group modal remained opened after deleting the Group
• Fixed an issue where users with Empty Topic permission were also allowed to Create Topics on the same scope
• Fixed an issue where users were logged out of Console when trying to access Datamasking without permission

Console 1.17.3​

Release date: 2023-08-21

Features ✨​

• Replace the alert threshold column with the full underlying query in the 'Alerts' table.
• When creating alerts, you can now type in the dropdown selection of the resource (e.g. topic name, consumer group name) to improve usability when creating/editing alerts.

Fixes 🔨​

• Fix a case whereby saving alert did not preserve the consumer group name filter. Instead, saving or editing an existing alert would default to 'all consumer groups'.
• Fix N/A representation of delay (lag/s) for consumer groups in 'Apps Monitoring' to be more helpful. Lag is now labelled as 'infinite' in cases whereby lag exists in the group, but no new data is being received and no members exist in the consumer group.
• Remove the default alert 'No consumer group should be more than 3 minutes behind' for new clusters added to your environment. This was causing false positives in customers environments (e.g. non-production groups) and therefore it's advised to set alerts on explicit groups you wish to be alerted on. For existing clusters, if the alert is causing you to be notified on groups you do not wish for, then it's recommended to deactivate this alert.

Known issues ⚙️​

• Upon adding a new Kafka Cluster, Built-in Alerts & Custom Alerts are not working. You must restart Conduktor after adding the Kafka Cluster for changes to take effect.

Console 1.17.2​

Release date: 2023-08-04

Fixes 🔨​

• Fixed an issue on the consumer group list screen which could inflate the number of members in a group. This was a result of migrating to the internal 'snapshot' cache for improved performance, and missing a case whereby we did not clean up old consumer group members.

Known issues ⚙️​

• Upon adding a new Kafka Cluster, Built-in Alerts & Custom Alerts are not working. You must restart Conduktor after adding the Kafka Cluster for changes to take effect.

Console 1.17.1​

Release date: 2023-07-28

Features ✨​

Overhauled RBAC (Role-Based Access Control)​

Our new RBAC has finally arrived! The previous roles 'Editor' and 'Viewer' have been remapped to granular permissions for each associated resource.

You can now precisely configure everything Conduktor & Kafka related to perfectly fit your requirements.

More details can be found on the docs site.

Give us feedback on this feature here.

Public APIs & Support for Automation​

We have opened Conduktor to being controlled using APIs.

The first iteration covers the following resources:

• Manage Clusters
• Manage Users, Groups and their respective Permissions (linked with our new RBAC!)

To start using the Conduktor API, navigate to API Keys in Settings and generate a new API Key.

Open API documentation portal is available on /docs of your deployment (i.e. http://localhost:8080/docs).

Fow now, only members of the Admin group can generate API Keys and access the API.

Give us feedback on what you would like to see in the API next here. You can also refer to the docs here.

The following example lists the permissions associated to your group "project-a".

curl -X GET http://localhost:8080/public/v1/groups/project-a/permissions -H "Authorization: Bearer {token}"
[
    {
        "resourceType": "Topic",
        "clusterId": "local",
        "topicPattern": "projectA-*",
        "permissions": [
            "topicConsume",
            "topicViewConfig"
        ]
    },
    {
        "resourceType": "ConsumerGroup",
        "clusterId": "local",
        "consumerGroupPattern": "projectA-*",
        "permissions": [
            "consumerGroupView"
        ]
    }
]

 

Major performance boost to both the Topic and Consumer Group List pages​

Topic List and Consumer Group List are now served by snapshots which lead to a huge performance boost!

To limit the impact on your Kafka Cluster, we have switched from direct AdminClient calls to an intermediate snapshot that we refresh every 30seconds behind the scenes.

You should see a major performance improvement when listing your Topics and Consumer Groups, especially in larger environments. The snapshot serves all of your users which will drastically reduce the number of AdminClient calls in parallel and is updated every 30s.

Service Accounts Page​

A new "Service Accounts" item is available in the menu under ACLs. This is a new presentation of the ACLs, grouped by Service Accounts to drastically improve readability. For now it's read-only, so continue to use the ACLs page if you want to Create/Delete ACLs.

Let us know if you want more from this feature by providing feedback.

Table View in Consume with Quick Filters​

When you click a message in the Consume page, you will now see the Table Structure view of the message.

This works for most serializers that render JSON-compatible structures.

Along with each key-value line, you will also have the option to build a filter directly from the message data.

Precision regarding the timestamp timezone​

In order to prevent confusion regarding the timestamp of the message, we have renamed the column 'Timestamp' to 'Timestamp (Local)'. This shows the timestamp in your browser's timezone configuration.

To further alleviate any doubt, you can also mouse over the timestamp in the Consume page, which will present you with the ISO DateTime in UTC.

Fixes 🔨​

• Fixed a UI issue where Clusters configurations that use Kerberos or Oauth did not render properly
• Fixed a regression where Kafka password was displayed in the logs
• Disabled IPV6 listener in the docker image
• Fixed a bug preventing to access Consumer Group Details page from the Consumer Groups tab in Topics Details page
• Added Connection Pooling to reduce the number of active connections to the database by 25%
• Removed an error message in Broker page when there was no partition on the cluster
• Added support for Amazon RDS Proxy

Known issues ⚙️​

• Upon adding a new Kafka Cluster, Built-in Alerts & Custom Alerts are not working. You must restart Conduktor after adding the Kafka Cluster for changes to take effect.

Console 1.16.3​

Release date: 2023-07-03

Features ✨​

Config ID maps to technicalID​

When configuring initial setup using a .YAML, the id value will now map to the technicalID of the cluster setup.

clusters:
  - id: eastern-horizon
    name: My Local Kafka Cluster
    color: '#0013E7'
    bootstrapServers: kafka:9093

Set idle session timeout​

Configurable maximum session lifetime for authentication was introduced in 1.16.1. You can now additionally set a value for idle session timeout. This will log your users out of Conduktor if they are inactive for a user-defined period of time. Read about how to use these new configurations in the docs.

Fixes 🔨​

• Large topic list handling. Some of our latest and greatest work wasn't playing nicely when the number of topics was high, we've fixed that
• Improved offline environments. Some customers were experiencing issues when using completely offline environments, we've made some improvements to error handling, the error messages displayed and how we work with timeouts
• Connector restart history. One of our latest features for automatic connector restarts gave you all the lovely history so you can see what's going on, perhaps too much ;). We've refined this so that each connector only displays it's own history
• Connect first cluster improvements. When connecting your first cluster there were a few too many buttons available to click, which didn't take you where you wanted to go. We have disabled more of those to make it even clearer on how to get connected
• App version label restored. Some of you have noticed the app version label in the UI was removed and want it back, we hear you. You'll now find the current version of Console back where it was before, in the bottom left corner of the UI
• Squashed a bug with trailing slashes getting stuck on blank pages
• Improved error handling for tokens expiring
• Fixed a bug that prevented you to browse consumer groups with an empty name

Console 1.16.1​

Release date: 2023-06-16

Features ✨​

• Automatic connector restarts
• New home experience
• Configurable max session lifetime
• New 'by broker' view
• Show offsets in consumer group details

Automatic connector restarts (Beta feature)​

Failed Connector tasks could already be restarted from within Console at the click of a button.

Simply navigate to the instance of interest, click into it and from here you can manually restart.

Being able to manually restart from our UI without having to look elsewhere in your Kafka ecosystem is powerful, but we now have the ability for automatic connector restarts to be enabled!

You can configure Console to attempt to restart failed tasks as frequently as every ten minutes. If they are failing more frequently than this we suspect you have bigger issues to look into. 👀

And if that wasn't enough, we even differentiate between automatic and manual restarts within the connector.RestartedTask audit event.

New Home experience​

The Console home experience has been reworked to get you where you want to go quickly!

From the homepage you can now jump straight into connecting your clusters, viewing your most recent topics, or managing users, groups and permissions. You will also find a few more handy quick links 👀

Configurable max session lifetime​

You can now configure the maximum session lifetime for your users. This means your users will be forced to re-authenticate after a maximum period that you define.

See the documentation on how to configure this value. Note that the current default value is set to 3 days.

New 'by broker view'​

We have now added a new view in the Topics > Partitions tab that enables you to see a breakdown of partition leaders and partition replicas at a broker level.

Show offsets in Consumer Group details​

The Consumer Group details page has now been enriched with the 'End Offset' and the 'Committed Offset' for each Topic and Partition.

Fixes 🔨​

• Fix the JQ filter in Console
• Fix showing metrics for consumer groups with blank name
• Slack channel alerting now supports 500 channels, previously it was restricted at 100

Monitoring​

Features ✨​

Object storage support for external storage​

You can now configure monitoring to export data to other additional object storage providers such as GCS, Azure and Swift. This builds on what was previously only support for S3.

Fixes 🔨​

Alert channel list increased to 500​

• Fixed an issue when settting up alerts you could only pick from the first 100 channels that were available, now the list allows selection from up to 500.

Console 1.15.0​

Release date: 2023-05-15

Conduktor version 1.15.0 is now available, introducing various new features and optimizations. This release brings an enhanced Audit experience to Enterprise customers, data export functionality into Console, and organization-wide tagging of resources. See the full list of changes and release notes below.

Important changes ❗​

• Note that in 1.15.0, the Testing application will no longer be started by default in the on-premise deployment. This provides a performance optimization for those customers that are not currently using Testing. If you wish to start Testing alongside Conduktor, you should set an explicit environment variable.

Features ✨​

Give us feedback here

• Admin

  • Audit Log has been completely revamped and enriched. Events now contain relevant contextual information (upon click), and logs can now be filtered by a range of criteria (user, resource type, resource name, event, cluster and date).

• Console

  • Tags are now organization-wide, meaning visibility of this additional metadata is shared amongst colleagues in your organization. See the docs for more information.
  • You can now export data in either CSV or JSON format via the Consumer view. See the docs for information on how.
  • When using multiple JS filters in the Consumer view, these are now combined with logical AND instead of OR.
  • New experience for showing statistics on each resource that enables more of the screen to be used for displaying data.
  • Cluster selection RBAC: Visibility of clusters that can be selected now depends on the users data permissions applied through RBAC.

• Testing

  • Testing is now disabled by default when starting Conduktor. To start Testing alongside Conduktor, you should set an explicit environment variable.
  • Note that in Conduktor 1.15.0, the Testing application will no longer be started by default on our on-premise deployment. It's still available on our Cloud version.

If you wish to start Testing alongside the Platform on-premise, you must start Conduktor using an explicit environment variable.

How to start Console with Testing?

Set the environment variable TESTING_ENABLED to true when starting Conduktor. See docker image environment variables.

Why are we making this change?

By removing the number of services started by default on-premise, this provides a performance optimisation for customers that are not currently using Testing.

---

• Monitoring

  • All monitoring metrics are now provided without any agent dependencies

Fix 🔨​

• Platform

  • CVEs fixes

• Console

  • Support negative lag in consumer groups (cases whereby the last committed offset is greater than the latest offset)
  • Security fix to stop exposing cluster configuration inside the UI.

• Monitoring

  • Computation of URP metric is set to 0 if we find confluent.log.placement.constraints in the cluster config or confluent.placement.constraints in the topic config. This avoids raising a false positive alert in case of a multi-region Confluent cluster. Note this logic will also be applied in Console in the next release.

• Governance

  • Do not show error toast in Data Masking when a user/group no longer exists in a policy.

• Admin

  • Accept "/" character in consumer group name

Console 1.14.0​

Release date: 2023-04-17

Conduktor version 1.14.0 is now available, introducing various new features and enhancements. This release includes performance improvements in the Console for loading Kafka data, support for MS Teams integration, the ability to add SSO users to your organization before their first login, and a simple onboarding wizard for easy setup. Important changes in this version include the requirement to update the configuration to define a root administrator. Check out the full list of changes below and update to Conduktor 1.14.0 to enjoy these new features and improvements.

Important changes ❗​

• This version requires a configuration update to ensure you have root administrator defined. This is mandatory for initialization of the platform, therefore you MUST update your configuration prior to upgrading.

Features ✨​

Give us feedback here

• Platform

  • See important changes above. You must ensure you have a root administrator defined in your platform configuration.
  • New onboarding wizard to help setup your environment for a new installation. This can be used to configure license, organization, database and SSO (Oauth2/LDAP) from inside the Conduktor UI. See docs.
  • Added a memory available check at startup to prevent platform running in cases whereby the memory available is less than the memory required by the RUN_MODE being used.

• Console

  • Long resource names are now wrapped to ensure the full string is always visible in the table.
  • We have improved the performance of loading topic names and associated metadata in the topic list screen.
  • We have improved the performance for loading subjects from schema registry.

• Admin

  • It's now possible to add an SSO user to your organization before their first login. This allows you to allocate appropriate permissions prior to their first login. See docs.
  • Notifications screen is now 'Integrations', with support added for Microsoft Teams. See docs

• Monitoring

  • Request confirmation from users when deleting alerts.
  • Reduced verbosity of logs from the topic scanner.
  • Integration of Microsoft Teams notifications for alerting.

Fix 🔨​

Console 1.13.2​

Release date: 2023-03-31

Conduktor version 1.13.2 is now available, bringing bug fixes and improvements for the Platform, Console, and Admin solutions. The Platform fixes include addressing a regression related to the platform database connection default schema and fetching OIDC user information during login. The Console now supports references in schemas and fixes the color of the cluster name in dark mode. The Admin solution has reduced verbosity in logs and eliminated cluster configuration leakage. Update to Conduktor 1.13.2 to benefit from these bug fixes and enhancements.

Fix 🔨​

• Platform

  • Fix regression on platform database connection default schema used if changed from PostgreSQL default
  • Now fetch OIDC user infos endpoint for user email claim if not present in ID Token during login.

• Console

  • Support references in Schemas
  • Dark mode: fix color of cluster name in cluster dropdown

• Admin

  • Logs: reduce verbosity and avoid cluster configuration leakage

Console 1.13.1​

Release date: 2023-03-17

Conduktor version 1.13.1 is now available, addressing bugs and improving HTTP proxy support. The Platform now correctly uses the configured external URL for SSO callback URL resolution, and OIDC SSO requests now utilize the CDK_HTTP_PROXY_* configurations. Additionally, improvements have been made to HTTP certificate migration and various test scenarios. Upgrade to Conduktor 1.13.1 for these bug fixes and enhancements.

Fix 🔨​

• Platform

  • Fix an issue whereby platform does not take hostname from platform.external.url. Now the configured external url is always used for SSO callback url resolution.
  • Fix an issue whereby CDK_HTTP_PROXY_* configurations were not being used for OIDC SSO requests. Also set CDK_HTTP_NON_PROXY_HOSTS default value to localhost|127.* when HTTP proxy is configured. See our Http Proxy configuration documentation for more details.

• Testing

  • Fix migration for HTTP certs and some test scenarios

Console 1.13.0​

Release date: 2023-03-13

Conduktor version 1.13.0 is now available, featuring performance improvements in the Console and the ability to sync Conduktor groups with external groups from LDAP/OAuth2.0 identity providers. This release also introduces new features such as external group mapping, DB support for TLS, and the option to force platform URLs. Additionally, improvements have been made to the Kafka Connect connection configuration and testing functionalities. Upgrade to Conduktor 1.13.0 for these exciting new features and fixes.

Important changes ❗​

• This version replaces platform.fqdn configuration with platform.external.url (used for SSO callback URL when using a reverse proxy).

Features ✨​

Give us feedback here

• Platform

  • External group mapping for LDAP/OIDC - See docs
  • DB support for TLS - See docs
  • Allow to force platform URL with platform.external.url configuration. This can fix SSO callback URL errors if upstream proxy sends the wrong X-Forwarded-* HTTP headers to the platform.

• Console

  • Support mTLS on Kafka Connect
  • Improve the performance of the consumer and topic lists screen
  • New design for the cluster dropdown has been implemented

Important change when updating to Conduktor 1.18.0 (September 14th, 2023)​

Monitoring​

We are cleaning up our Docker image to bring you a simpler, lighter, and generally more operable product.

In that regard, we have extracted the 'Storage & Alerting' aspect of the Monitoring Solution from the base Console image and moved it to a dependency image.

Consequences:

• If you didn't use Monitoring: No further action is required on your part. You won't be able to access the Monitoring module anymore.
• If you used Monitoring: read the documentation to understand how to deploy and configure the dependency image conduktor/conduktor-console-cortex:1.18.0.

Embedded database​

As having a Postgres database is one of the production requirements we have, we decided to remove the embedded Postgres database from the Docker image. That way, having a Postgres database is now required to deploy Conduktor Console. If you want to get started and discover the product, here are guides for Docker and Kubernetes.

Testing​

In line with the deprecation of the Testing module, we have removed Testing from the base image.

Authentication​

Finally, we have rewritten our authentication module due to all those changes, to move to something far simpler. If you have any issues with authentication using LDAP or OIDC with this new release, please contact Conduktor Support.

Stay updated and leverage the full potential of Conduktor 1.2.0!

Load CSVs from S3 Compatible Storage​

Previously it was only possible to load a file from a location that was local to your testing Agent. This new option for loading data from S3 into a test scenario brings much more flexibility. Specifically, it unlocks a more appropriate method for loading external files in automated tests that run in your CI/CD pipeline.

Features ✨​

• Platform
  • Platform configurations can be overridden from environment variables (see configuration documentation)
• Testing
  • Simplify source selection in checks. Rather than remember the full jq prefix, we now provide a helper for the different data attributes you might want to test (message key, value, headers etc.)
  • Add support of S3 in LoadCSV task
  • Add a comparison data node that allows you to compare data across records consumed from 2 or more distinct topics.
