No recent discussions on these subjects, but I think it'll come in Flink 1.17

Shengkaiis the maintainer of SQL Client and SQL gateway, maybe he can provide

主题: SQL Gateway and SQL Client

Hi all,

I’m Alexey from Confluent. This is my first email in this discussion list.
I’m rather new to Flink, and to local customs of communication. I want to
dive deeper and hopefully get more involved over time.

Currently I have a few questions around SQL Gateway and SQL Client.
Specifically I wanted to learn what is the vision around the nearest future
of these two components.

In what Flink’s release the connection from SQL Client to the Gateway is
expected to be added? I was looking at
https://issues.apache.org/jira/browse/FLINK-29486, and recently it got
renamed from “Enable SQL Client to Connect SQL Gateway in Remote Mode” to
“Introduce Client Parser to get statement type”.  I did some search, but
didn’t find a good place where the client's work in this direction is
discussed or tracked.

A couple questions about the SQL Gateway. The FLIP-91
<https://cwiki.apache.org/confluence/display/FLINK/FLIP-91%3A+Support+SQL+Gateway#FLIP91:SupportSQLGateway-Futurework>
mentions “Authentication module” (2) and “Persistent Gateway” (4) as
possible future work. Were there any recent discussions on these subjects?
Or maybe there are some ideas how to move these directions forward? Another
related topic: are there ideas around making SQL Gateway a multi-tenant
component?

Thank you,

Alexey
