Duo Zhang commented on HBASE-18070: ----------------------------------- And I think here we could do much better than ‘HedgeRead’ solution. The ‘HedgeRead’ mode will always request to primary replica first, and then fallback to secondary replicas when it can not get the result back in time. This means all traffic will go to primary first until we make the primary replica down, we will go to secondary replicas. But here we will go to different replicas evenly, which should have better performance when the traffic could make a single replica down. Thanks. > Enable memstore replication for meta replica > -------------------------------------------- > > Key: HBASE-18070 > URL: https://issues.apache.org/jira/browse/HBASE-18070 > Project: HBase > Issue Type: New Feature > Reporter: Hua Xiang > Assignee: Huaxiang Sun > Priority: Critical > Fix For: 3.0.0-alpha-1, 2.4.0, HBASE-18070, HBASE-18070.branch-2 > > > Based on the current doc, memstore replication is not enabled for meta > replica. Memstore replication will be a good improvement for meta replica. > Create jira to track this effort (feasibility, design, implementation, etc). -- This message was sent by Atlassian Jira (v8.3.4#803005)
