---------------------------------
Summary: 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
Reporter: Duo Zhang
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.
