[jira] [Reopened] (HBASE-25284) Check-in "Enable memstore replication..." design

["Duo Zhang (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-25284?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Duo Zhang reopened HBASE-25284:
-------------------------------

Reopen to update the design doc to explicitly mention that HedgeRead mode can not increase the throughput of meta qps as it will only request secondary replicas when primary replica can not return in time. But if the primary replica is overloaded then the whole cluster will be in trouble so it is useless to request secondary replicas. This is one of the most important goal of this issue.

My modification permission on the design doc has been removed to avoid spamming, so please update the design doc on google doc and commit it again to the code base [~huaxiangsun]. I'm not going to at stack again since he refused to do anything to solve the problem here, I do not want to waste any time.

Thanks.
