xuefuz commented on issue #9068: [FLINK-13195] Add create table support for SqlClient URL: https://github.com/apache/flink/pull/9068#issuecomment-510280822 I appreciate Timo's vision of client/server model even in case that we only have local execution at the moment. However, I'm a little curious about the goal of a stateless gateway with state being passed back and forth. Some state is easily fit to this model, while others, such as temporary tables created by the user that's further referenced in subsequent queries. This is just one thing that's currently maintained in a table env. Without a live table env instance maintained for a remote client, it's hard to maintain the state via a session context. To me, stateless gateway seems making a lot of sense for largely stateless client, like one submitting a streaming job. The scenario for batch can be quite different. Personally, I am in favor of having some DDL support now and leaving re-architecturing for the next release.
