pengcheng xiong created HIVE-7876:
-------------------------------------

             Summary: further improve the columns stats update speed for all the partitions of a table
                 Key: HIVE-7876
                 URL: https://issues.apache.org/jira/browse/HIVE-7876
             Project: Hive
          Issue Type: Improvement
            Reporter: pengcheng xiong
            Assignee: pengcheng xiong
            Priority: Minor


The previous solution https://issues.apache.org/jira/browse/HIVE-7736
is not enough for the case when there are too many columns/partitions.

The user will encounter 

org.apache.thrift.transport.TTransportException: java.net.SocketTimeoutException: Read timed out

We try to remove more of transaction overhead
