> Currently we support "transactional" keyword in CREATE TABLE command. But if not add "stored as ORC", the table created is insert_only.
> We want to add a feature that when table is transactional (either using "transanctional" keyword or adding tblproperties ('transactional'='true'), the table created by default will be ORC, and 'transactional_properties'='default'.
