> Could we write meta state info in savepoint meta?
----
[~yunta] [~liufangqi] I'm really glad to see the Community doing this kind of
discussion . Actually , we also did the same thing (adding meta information
such as state desc to the savepoint) in the internal Flink version of
ByteDance.The reason we did this in the first place was because now users need
to re-register the state using state-processor-api to query the state. We think
this is too diffcult for users. So we did some simple work to make it easier
for users to query state (such as add state meta to Savepoint or use Flink
Batch sql for state Query .so I personally agree with this idea.

> Now we can't get the State Descriptor info in the checkpoint meta. Like the

> Maybe there are other cases we need the State Descriptor, so can we add this
