>
> 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
> Priority: Major
>
> 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'.
