Yun Tang commented on FLINK-25360:
----------------------------------
[~liufangqi] Any changes to checkpoint persistent content requires attention to
consider backward compatibility. I think your request sounds more like related
to state-processor-API, could you give details on what current
state-processor-API cannot do to meet your request? Moreover, do you think we
can just change on state-processor-API to meet your request?

> 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?
