[jira] [Created] (KAFKA-14420) MirrorMaker should not clear filtered configs on target topics

Mickael Maison created KAFKA-14420:
--------------------------------------

             Summary: MirrorMaker should not clear filtered configs on target topics
                 Key: KAFKA-14420
                 URL: https://issues.apache.org/jira/browse/KAFKA-14420
             Project: Kafka
          Issue Type: Bug
          Components: mirrormaker
    Affects Versions: 3.3.1
            Reporter: Mickael Maison


If you set additional configurations on a remote topic, MirrorMaker will clear them when it syncs topic configurations.

The issue is that it also clears topic configurations that are filtered. For example this prevents running Cruise Control on the target cluster as it may set follower.replication.throttled.replicas and leader.replication.throttled.replicas.

MirrorMaker should not clear topic configurations that are filtered on the target cluster.
