Managing Topics in Confluent Cloud

You can create and edit Apache Kafka® topics by using the Confluent Cloud interface. The topics are grouped by cluster.

Important

In a VPC peered environment, topic management is disabled in the UI. However, you can use the Confluent Cloud CLI to manage topics. For more information, see the Confluent Cloud limits and supported features.

  3. Make your changes and click Save changes. By default, only the most commonly modified settings are shown. For advanced settings, scroll to the bottom of the page and click Switch to expert mode.

    Important

    Some topic configuration parameters are not configurable through this interface. These unmodifiable parameters display a lock symbol (lock) next to them. They cannot be changed in either default or expert mode.
