Randall Hauch updated KAFKA-9076:
---------------------------------
    Fix Version/s:     (was: 2.6.0)
                   2.7.0

Since this is not a blocker issue, as part of the 2.6.0 release process I'm changing the fix version to `2.7.0`. If this is incorrect, please respond and discuss on the "[DISCUSS] Apache Kafka 2.6.0 release" discussion mailing list thread.

> To calculate the translated consumer offset in the target cluster, currently `Mirror-client` provides a function called "remoteConsumerOffsets()" that is used by "RemoteClusterUtils" for one-time purpose.
> In order to make the consumer and stream applications migrate from source to target cluster transparently and conveniently, e.g. in event of source cluster failure, a background job is proposed to periodically sync the consumer offsets from the source to target cluster, so that when the consumer and stream applications switch to the target cluster, it will resume to consume from where it left off at source cluster.
