On top of the table you have different fields to help you:

Raw view button

More Button ...
This lets you do the same 3 operations that are available on the Topic List Page : Add partitions, Empty Topic and Delete Topic.

Edit configurations​

When clicking on the edit button from the table rows, a new screen will appear with the following details:

  • The name and description of the topic configuration
  • The Kafka default value
  • The current value

You can choose to either Update the value to something new or revert to the Kafka default, which will apply the change directly on the Kafka cluster, similarly to the kafka-configs commands below.

# Update value
$ kafka-configs --bootstrap-server broker_host:port \
  --entity-type topics --entity-name my_topic_name  \
  --alter --add-config cleanup.policy=<new-value>

# Reset to default
$ kafka-configs --bootstrap-server broker_host:port \
  --entity-type topics --entity-name my_topic_name  \
  --alter --delete-config cleanup.policy
