-------------------------------
Resolution: Invalid
> Introduce a new API to sync the live region server list more effectively
> ------------------------------------------------------------------------
>
> Key: HBASE-26011
> URL: https://issues.apache.org/jira/browse/HBASE-26011
> Project: HBase
> Issue Type: Sub-task
> Components: master, Replication
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
>
> In HBASE-25976, we introduced a master based replication tracker to not
> depend on zk, but the problem is that we will always fetch the whole region
> server list, from every region server, which will become a performance issue
> when the cluster has lots of region servers.
> So we need to introduce a new API to sync the live region server list. As the
> region server list will not be changed too much, we should have a way to
> detect this and not pass the full list.
