Release date: 2025-03-05

New features​

  • New metric gateway.apiKeys.throttle_ms : sets the throttling time in Kafka responses per apiKey in milliseconds
  • Updated existing metric gateway.apiKeys.latency.request_response : sets the latency to process a request and generate a response for each API key
    • It now tracks latency for all verbs (eg CONNECTION) not just FETCH/PRODUCE

Feature changes​

  • Changes to Limit Commit Offset Plugin:
    • accuracy of rate limiting has been improved
    • action/throttleTimeInMs properties did not work correctly and are now ignored
  • Changes to cluster ACLs:
    • when creating cluster ACLs using a programmatic API, only allow kafka-cluster for the name part of the resource. This makes Gateway consistent with Kafka.

Fixes​

  • Fixed a problem with the Create Topic Policy plugin which would not apply overrides to default configurations from the underlying Kafka setup.
  • Fixed a problem with CreateTopics ACLs in Gateway which previously also required the Create cluster permission enabled.
  • Addressed a problem with Non Delegated SASL/PLAIN token credentials, where Gateway would continue to work after service account has been deleted. To enable this feature set the environment variable GATEWAY_USER_POOL_SERVICE_ACCOUNT_REQUIRED to true (it currently defaults to false).
  • Fixed a problem in AddPartitionsToTxnRequest where ACLs on transactionIds in new location were not being checked when Kafka API version was >= 4.
  • An un-authorized idempotent producer will now throw a ClusterAuthorizationException instead of a TransactionalIdAuthorizationException, making Conduktor Gateway consistent with Kafka.
