[jira] [Commented] (HBASE-23326) Implement a ProcedureStore which stores procedures in a HRegion

    [ https://issues.apache.org/jira/browse/HBASE-23326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16996766#comment-16996766 ] 

Sean Busbey commented on HBASE-23326:
-------------------------------------

Can we get some kind of design doc or overview doc of goals and approach? I think one of the big tripping up points for the existing procedure store is that folks have to start at the code without any real guideposts.

> So we can resue the code in HRegion for persisting the procedures, and also the optimized WAL implementation for better performance.
> This requires we merge the hbase-procedure module to hbase-server, which is an anti-pattern as we make the hbase-server module more overloaded. But I think later we can first try to move the WAL stuff out.
