> Implement DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP for kudu
> ----------------------------------------------------------------------------
>
> Key: KUDU-2908
> URL: https://issues.apache.org/jira/browse/KUDU-2908
> Project: Kudu
> Issue Type: New Feature
> Reporter: ZhangYao
> Assignee: ZhangYao
> Priority: Major
>
> Implement DEAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP just like
> in MYSQL.
> Here is the reference.
> https://dev.mysql.com/doc/refman/8.0/en/timestamp-initialization.html
> This feature can be helpful when user want an automatic timestamp column and
> can be used for further TTL.
> It works like this:
> 1. Whether DEFAULT CURRENT_TIMESTAMP is set or ON UPDATE CURRENT_TIMESTAMP is
> set, will create a timestamp column for table.
> 2. If only DEFAULT CURRENT_TIMESTAMP is set, then will get kudu time when
> insert.
> 3. If only ON UPDATE CURRENT_TIMESTAMP is set, then it will have default
> value and will update timestamp column when update.
> 4. If both set, then it will get kudu time when insert and update timestamp
> when update.
