Key: HIVE-2430
URL: https://issues.apache.org/jira/browse/HIVE-2430
Project: Hive
Issue Type: Bug
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
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.
