[jira] [Created] (HIVE-28371) Optimize add partitions authorization in HiveMetaStore

Sai Hemanth Gantasala created HIVE-28371:
--------------------------------------------

             Summary: Optimize add partitions authorization in HiveMetaStore
                 Key: HIVE-28371
                 URL: https://issues.apache.org/jira/browse/HIVE-28371
             Project: Hive
          Issue Type: Improvement
          Components: Standalone Metastore
            Reporter: Sai Hemanth Gantasala
            Assignee: Sai Hemanth Gantasala


Currently add_partitions() api sends all the partitions (new partitions and existing partitions) that need to be added for authorization, instead, we can optimize this by sending only the new partitions for authorization.

Impact: Alter table recover partitions collects all the available partitions and sends it to Metastore to check if any new partitions can be added. If all the partitions are sent for authorization irrespective of whether it exists or not, the Authorization service will unnecessarily spend time on authorizing already existing partitions. This can be avoided by only authorizing new partitions.
