[jira] [Created] (HIVE-18453) ACID: Add "CREATE TRANSACTIONAL TABLE" syntax to unify ACID ORC & Parquet support

------------------------------

             Summary: 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


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.
