Thanks for the review @Myasuka > My main concern is how to handle the rescaling case? As same state could have different short state id in different subtasks. Good point. I addressed this with the backend UUID (discussed in [this thread](https://github.com/apache/flink/pull/17203#discussion_r707877114)). > Since we use key-group as the core design in rescaling, maybe we could combine it with group info. I think using key groups could be more fragile than backend UUID because they can be re-assigned multiple times (with multiple rescalings). Besides that, that would require more space in snapshot because state name would be written the number of times the number of key group assigned. -- This is an automated message from the Apache Git Service.
