> 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.
