刘方奇 commented on FLINK-25360:
-----------------------------
[~yunta] THX for your reply, actually I don't understand why RocksDB
incremenatl checkpoints already have enough information in checkpoint meta. As
I see, there are still not enough info in RocksDB incremenatl checkpoint meta
such as UDF.
Reply to your two lines:
# Is it means all state meta info will be stored in the checkpoint / savepoint
meta, if the discussion is agreed.
# How to start the discussion threads in dev mailing list? Could you help to
give a guide?
Wish all of you a happy new year and a merry Christmas in advance.

> Now we can't get the State Descriptor info in the checkpoint meta. Like the
> case if we use state-processor-api to load state then rewrite state, we can't
> flexible use the state.
> Maybe there are other cases we need the State Descriptor, so can we add this
> info?
