> KIP-1378: Consumer Group Renaming in MirrorMaker2
> -------------------------------------------------

> Key: KAFKA-21127

> Project: Kafka
> Issue Type: Improvement
> Components: mirrormaker
> Reporter: Edoardo Comar
> Assignee: Edoardo Comar
> Priority: Major
>
> 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/]`).
