Keith Turner created ACCUMULO-1607:
--------------------------------------

             Summary: reusue iterator stack when checking conditional mutations
                 Key: ACCUMULO-1607
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1607
             Project: Accumulo
          Issue Type: Sub-task
            Reporter: Keith Turner
             Fix For: 1.6.0


When checking if a conditional mutation should be applied a read is done on the tablet server using the iterators stack.  The conditional writer passes batches of mutations.  An optimization to the conditional writer would be to reuse the iterator stack when processing multiple mutation for the same tablet.
