[jira] [Created] (HBASE-10623) Add ability to read a row after applying a RowMutation

Michael Webster created HBASE-10623:
---------------------------------------

             Summary: Add ability to read a row after applying a RowMutation
                 Key: HBASE-10623
                 URL: https://issues.apache.org/jira/browse/HBASE-10623
             Project: HBase
          Issue Type: Improvement
            Reporter: Michael Webster
            Priority: Minor


It would be useful to be able to return a row to the user after all of the mutations in a RowMutation operation has been applied.  This would be similar to transactions in Redis where the result of executing an operation is returned to the user.  However, since RowMutations only affect a single row, only the final result would need to be returned.  This could allow for a snapshot view of the row without requiring any timestamp manipulation, or a second read by the client.

Looking at the implementation of RowMutations, it seems like the Get could be done after the write has been committed but before the row locks are released.
