--------------------------------------
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.
