Configure Topics Using Control Center for Confluent Platform

View and edit the configuration settings for topics.

Important

Some topic configuration parameters are not configurable through the Control Center UI. These unmodifiable parameters display a lock symbol (lock) in the text entry box. They cannot be changed in either default or custom expert mode. See Configurable topic parameters.
