------------------------------------
FYI we do have one ongoing diff to make those coordinator sticky on instance.id

> Make Round-robin / RangeAssignor to be "sticky" (part 5)

> Key: KAFKA-8495
> URL: https://issues.apache.org/jira/browse/KAFKA-8495
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Guozhang Wang
> Priority: Major
>
> For this new algorithm to be effective in reducing rebalance costs, it is
> really expecting the plug-in assignor to be "sticky" in some way, such that
> the diff of the newly-assigned-partitions and the
> existing-assigned-partitions can be small, and hence only a few subset of the
> total number of partitions need to be revoked / migrated at each rebalance in
> practice – otherwise, we are just paying more rebalance for little benefits.
