----------------------------------------

             Summary: Unify Binary format for Keyed State savepoints
                 Key: FLINK-20976
                 URL: https://issues.apache.org/jira/browse/FLINK-20976
             Project: Flink
          Issue Type: New Feature
          Components: Runtime / Checkpointing, Runtime / State Backends
            Reporter: Dawid Wysakowicz
             Fix For: 1.13.0


The main goal of this proposal is the following:

* Unify across all state backends a savepoint format for keyed state that is more future-proof and applicable for potential new state backends. Checkpoint formats, by definition, are still allowed to be backend specific.
* Make it possible to switch a state backend via a savepoint
* Rework abstractions related to snapshots and restoring, to reduce the overhead and code duplication when attempting to implement a new state backend.
