------------------------------------------

             Summary: Reduce overhead of adding notification log for update partition column statistics
                 Key: HIVE-25204
                 URL: https://issues.apache.org/jira/browse/HIVE-25204
             Project: Hive
          Issue Type: Sub-task
          Components: Hive, HiveServer2
            Reporter: mahesh kumar behera
            Assignee: mahesh kumar behera


The notification logs for partition column statistics can be optimised by adding them in batch. In the current implementation its done one by one causing multiple sql execution in the backend RDBMS. These SQL executions can be batched to reduce the execution time.
