[jira] [Commented] (HBASE-23697) Document new RegionProcedureStore operation and migration

    [ https://issues.apache.org/jira/browse/HBASE-23697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17016378#comment-17016378 ] 

Michael Stack commented on HBASE-23697:
---------------------------------------

It moves ProcedureStore Region WALs to archive with a '$masterproc$' suffix. Their TTL differs from that of our usual WALs. HFile archiver just deletes the buried Region files.

> Add a few notes to the refguide on the new RegionProcedureStore, how it works (A 'Region' but buried in the Master with dedicated flushing/compacting threads and archivers for WAL and hfile), how it differs from WALPS, and note it auto-migrates and there should be new issue moving on to the new store.
> Mention the configuration. Mention it is on WALFS even though it is a 'Region', etc.
