> 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
> Priority: Major
> Labels: ACID, Metastore, Streaming
> 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.
