[jira] [Created] (HBASE-24554) Improve/stable read replica

Huaxiang Sun created HBASE-24554:
------------------------------------

             Summary: Improve/stable read replica
                 Key: HBASE-24554
                 URL: https://issues.apache.org/jira/browse/HBASE-24554
             Project: HBase
          Issue Type: Task
          Components: read replicas
    Affects Versions: 2.3.0
            Reporter: Huaxiang Sun
            Assignee: Huaxiang Sun


Tracing some read replica issues recently, this is the umbrella Jira to track this effort. A few observations so far:
 # balancer balances replica regions too often, need to spend time on it. Replica region does not serve write and rarely serve reads (unless the client specifically selects the replica region). So data locality should be a very minimum factor for replica regions. 
 # Need to study split/merge for regions with replica, need to make them more robust. With proc-v2, probably it is already robust.
