Igor Kryvenko commented on HIVE-18453:
--------------------------------------
[~ekoifman] Thanks for the explanation again. Just to clarify, do you want that {{create transactional
table}} will create {{insert_only}} table? In this case, we will get exception *{{Attempt
to do update or delete on table default.target that is insert-only transactional}}*
> ACID: Add "CREATE TRANSACTIONAL TABLE" syntax to unify ACID ORC & Parquet support

> 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.
