Not sure why but seems the original thread can only be replied by me... So open a new one, copied several important information here
https://issues.apache.org/jira/browse/HBASE-21512 > > "Reimplement sync client based on async client" > > The jira title tells everything. This is what I promised when I first > introduced the async client in HBase, about three years ago, that the sync > client can be implemented on top of the async client, so we can remove the > old sync client implementation, which can reduce our client code base a lot. > > I've already opened a PR here, and received several feedback(thanks stack!) > > https://github.com/apache/hbase/pull/287 > > It shows that we add 8,663 lines and remove 31,386 lines. > > This is the flaky dashboard for this branch > > > https://builds.apache.org/job/HBASE-Find-Flaky-Tests/job/HBASE-21512/lastSuccessfulBuild/artifact/dashboard.html > > With the recent efforts I think it is getting better. > > After applying HBASE-22577 the performance is good enough now. And the > YCSB workloada also shows that there are no big differences on performance. > Please see the comments on HBASE-22564 for more details. And the release note is also ready. Stack and Josh have already voted +1, so we still need one more +1 to get this merged. Thanks a lot. > >
