Sorry for the late response. In the next version(Flink 1.17), we plan to support the SQL Client to submit the statement to the Flink SQL Gateway. The FLINK-29486 <https://issues.apache.org/jira/browse/FLINK-29486> is the first step to remove the usage of the `Parser` in the client side, which needs to read the table schema during the converting sql node to operation. I think the authentication module is not part of our plan in 1.17 because of the busy work. I think we'll start the design at the end of the release-1.17. But could you share more details about the requirements of the authentication? - Do you use the kerberos or delegation token or password to do the authentication? - After the authentication, do you need the sql gateway to submit the job on behalf of the client? - ...
For detailed implementation, I think Hive and Presto are good examples to dig in. If you have some thoughts about the authentication module, please let me know.
