刘方奇 commented on FLINK-25360:
-----------------------------
[~mayuehappy] THX for your reply, you are right. If the info is store in the
state file only that we can not get this simply as the state file may be so
huge. In most case, we want use this info locally. CheckpointMetadata is a tiny
file, and we can deserialize it simply.
> Add State Desc to CheckpointMetadata

> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing, Runtime / State Backends
> Reporter: 刘方奇
> Priority: Major
>
> 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?
