Summary: KIP-1378: Consumer Group Renaming in MirrorMaker2
Key: KAFKA-21127
URL: https://issues.apache.org/jira/browse/KAFKA-21127
Project: Kafka
Issue Type: Improvement
Components: mirrormaker
Reporter: Edoardo Comar
MirrorMaker 2 (MM2) provides pluggable topic renaming across clusters via the
`ReplicationPolicy` interface (e.g., `DefaultReplicationPolicy` prefixes topic
names with the source cluster alias `<source>.<topic>`, while
`IdentityReplicationPolicy` keeps them identical).
However, consumer groups do not have an equivalent pluggable naming mechanism.
Today, `MirrorCheckpointConnector` and `MirrorCheckpointTask` mirror consumer
group offsets to the target cluster preserving the exact source consumer group
ID (`[group.id|http://group.id/]`).
