             Summary: HiveEndPoint: Optimise opening batch transactions and getting write Ids for each transaction in the batch into single metastore api.
                 Key: HIVE-18752
                 URL: https://issues.apache.org/jira/browse/HIVE-18752
             Project: Hive
          Issue Type: Sub-task
          Components: HiveServer2, Metastore
    Affects Versions: 3.0.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan
             Fix For: 3.0.0


Per table write ID implementation (HIVE-18192) have introduced write ID and maps it against the txn.

Now, for streaming ingest, we need to open txns batch and then allocate write id for each txn in the batch which is 2 metastore calls.

This can be optimised to use only one metastore api.
