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.


This feature is disabled when the cluster is VPC peered. For more information, see Features and Capabilities.

Create a Topic

  1. From the Environment overview page, click your cluster name.

  2. Click the Topics page and click Create topic.

  3. Specify your topic details and click Create with defaults. For advanced topic settings, click Customize settings.


Modify a Topic

  1. Click the Topics page, click the ellipses (...) next to your cluster name, and click Settings.

  2. Click Edit settings.

  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.


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