Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).
Motivation:
Currently flink sql auxiliary statements has supported some good features such as catalog/databases/table support.
These features
...
have been a critical integration for Flink to be able to manage metadata like a classic RDBMS and make developers more easy to create or modify or list needed meta datas.
But these features are not very complete
...
compared with other popular engines such as spark, presto. And these improved features are very useful for users or developers.
