------------------------------------
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.
