In practice, I found that when I configure a mirror checkpoint connector, because the source cluster has a large number of group or the number of group under a topic changes frequently, the connector will frequently rebalance between its tasks, although there is no change in the synchronized group list of the configuration. I don't think connector should rebalance frequently in this case to affect group synchronization tasks without any group changes. In this PR, MirrorCheckpointConnector avoids the rabalance interference caused by the addition and deletion of irrelevant groups ([KAFKA-14837](https://issues.apache.org/jira/browse/KAFKA-14837)), and reduces the rpc calls of "listConsumerGroupOffsets" in each task about irrelevant groups ([KAFKA-14842](https://issues.apache.org/jira/browse/KAFKA-14842)). -- This is an automated message from the Apache Git Service.
