                 Key: DRILL-768
                 URL: https://issues.apache.org/jira/browse/DRILL-768

          Issue Type: Improvement
            Reporter: Aman Sinha


Drill currently supports 2 phase aggregation for SUM, MIN, MAX.  This enhancement is to support 2 phase COUNT aggregates.   In Phase 1 we will do partial count.  In Phase 2 we need to sum the partial counts to produce the final count.
