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

             Summary: Unify serialization format of savepoint for switching state backends
                 Key: FLINK-11254
                 URL: https://issues.apache.org/jira/browse/FLINK-11254
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 1.7.1
            Reporter: Congxian Qiu
            Assignee: Congxian Qiu


For the current version, the serialization formats of savepoint between HeapKeyedStateBackend and RocksDBStateBackend are different, so we can not switch state backend when using savepoint. We should unify the serialization formats of the savepoint to support state backend switch.
