-------------------------------------
Summary: Use ORC file format by default when creating transactional table
Key: HIVE-23765
URL: https://issues.apache.org/jira/browse/HIVE-23765
Project: Hive
Issue Type: New Feature
Components: HiveServer2
Affects Versions: 4.0.0
Reporter: Xiaomeng Zhang
Assignee: Xiaomeng Zhang
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'.
