---------------------------------------
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.
