             Summary: Optimize add_partitions related api in HMS
                 Key: HIVE-27500
                 URL: https://issues.apache.org/jira/browse/HIVE-27500
             Project: Hive
          Issue Type: Improvement
          Components: Hive
            Reporter: Wechar
            Assignee: Wechar


{{HMSHandler}} has three APIs for add partitions: {{add_partitions_req}}, 
{{add_partitions}} and {{add_partitions_pspec}}. Currently both 
{{add_partitions_req}} and {{add_partitions}} APIs invoke 
{{add_partitions_core}} function which was improved by direct sql in HIVE-26035.

We can also invoke {{add_partitions_core}} function within 
{{add_partitions_pspec}} API for performance improvement.
