             Summary: Storing mm2 topics on source side
                 Key: KAFKA-16193
                 URL: https://issues.apache.org/jira/browse/KAFKA-16193
             Project: Kafka
          Issue Type: Improvement
          Components: mirrormaker
            Reporter: Mikhail Filatov


We have 2 Kafka clusters and one of them is external. We use Mirror Maker to 
replicate one topic from our Kafka to external one but Mirror Maker also 
creates its service topic on target side (mm2-configs.source.internal, 
mm2-offsets.source.internal, mm2-status.source.internal topics).

We would like to keep such topics on our source side, but as I understand it is 
not configurable and topics created only on target side - 
[https://github.com/apache/kafka/blob/3.5/connect/mirror/src/main/java/org/apache/kafka/connect/mirror/MirrorMakerConfig.java#L182]

If we can manage workerConfig and specify the side where such topics to keep, 
it could solve the problem.
