Duo Zhang resolved HBASE-28212. ------------------------------- Resolution: Fixed Pushed the addendum to branch-2.6. > Do not need to maintain rollback step when root procedure does not support > rollback > ----------------------------------------------------------------------------------- > > Key: HBASE-28212 > URL: https://issues.apache.org/jira/browse/HBASE-28212 > Project: HBase > Issue Type: Improvement > Components: master, proc-v2 > Reporter: Duo Zhang > Assignee: Duo Zhang > Priority: Major > Fix For: 2.6.0, 2.4.18, 3.0.0-beta-1, 2.5.7 > > > In HBASE-28210, we need to synchronized on RootProcedureState when updating > procedure store, which will decrease the performance a lot when there are > lots of sub procedures for a procedure, such as SCP, so it will impact MTTR. > But actually, SCP does not support rollback, so I do not think we need to > maintain this information. If so, I think we do not need the synchronization > added in HBASE-28210, at least for SCP then. This could get the performance > back. -- This message was sent by Atlassian Jira (v8.20.10#820010)
