[~gopalv] Hi. Can I take this JIRA?
> ACID: Add "CREATE TRANSACTIONAL TABLE" syntax to unify ACID ORC & Parquet support
> ---------------------------------------------------------------------------------
>
> Key: HIVE-18453
> URL: https://issues.apache.org/jira/browse/HIVE-18453
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Reporter: Gopal V
> Priority: Major
>
> The ACID table markers are currently done with TBLPROPERTIES which is inherently fragile.
> The "create transactional table" offers a way to standardize the syntax and allows for future compatibility changes to support Parquet ACIDv2 tables along with ORC tables.
> The ACIDv2 design is format independent, with the ability to add new vectorized input formats with no changes to the design.
