      Description

      After JIRA HIVE-2144 (https://issues.apache.org/jira/browse/HIVE-2144), the performance in stats DB degraded significantly due to MySQL's inefficient index maintenance.

      We should remove the primary index introduced in that JIRA and resolve duplicates in the stats aggregation
      phase.
