Andrew Purtell created HBASE-12972:
--------------------------------------

             Summary: Region, a supportable public/evolving subset of HRegion
                 Key: HBASE-12972
                 URL: https://issues.apache.org/jira/browse/HBASE-12972
             Project: HBase
          Issue Type: New Feature
            Reporter: Andrew Purtell


On HBASE-12566, [~lhofhansl] proposed:
{quote}
Maybe we can have a {{Region}} interface that is to {{HRegion}} is what {{Store}} is to {{HStore}}. Store marked with {{@InterfaceAudience.Private}} but used in some coprocessor hooks.
{quote}

By example, now coprocessors have to reach into HRegion in order to participate in row and region locking protocols, this is one area where the functionality is legitimate for coprocessors but not for users, so an in-between interface make sense.

In addition we should promote {{Store}}'s interface audience to LimitedPrivate(COPROC).
