Subject [jira] [Created] (HIVE-17341) DbTxnManger.startHeartbeat()
Date Thu, 17 Aug 2017 01:11:00 GMT
Eugene Koifman created HIVE-17341:

             Summary: DbTxnManger.startHeartbeat()
                 Key: HIVE-17341
             Project: Hive
          Issue Type: Improvement
          Components: Transactions
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman

This sets up a fixed delay for all heartebeats.  If many queries land on the server at the
same time,
they will wake up and start hearbeating at the same time causing a bottleneck.

Add some random element to heatbeat delay.
