> 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.
