-------------------------------------

             Summary: Add config option to disable server-side mutation 
processing
                 Key: PHOENIX-4595
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4595
             Project: Phoenix
          Issue Type: Improvement
            Reporter: James Taylor


Phoenix has an option to process a DELETE or an UPSERT SELECT to the same table 
purely on the server side. Though this prevents the need to return the row keys 
back to the client (reducing network traffic), it can also lead to the handler 
being tied up for a long period of time:
- if many mutations are being processed
- if the table has mutable indexes and the update to them fail (since the retry 
will happen on the server side).

We should provide a default to disable this optimization.
