> 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
> Priority: Major
>
> 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.
