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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
