[jira] [Created] (FLINK-25872) Restoring from incremental checkpoint with changelog state-backend cannot work well with snapshot CLAIM mode

Yun Tang created FLINK-25872:
--------------------------------

             Summary: Restoring from incremental checkpoint with changelog state-backend cannot work well with snapshot CLAIM mode 
                 Key: FLINK-25872
                 URL: https://issues.apache.org/jira/browse/FLINK-25872
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing, Runtime / State Backends
            Reporter: Yun Tang


If we restore from incremental checkpoint with changelog state-backend enabled in snapshot CLAIM mode, the restored checkpoint would be discarded on subsume, which lead to the private state in Incremental state handle could be deleted by mistake. This bug is like FLINK-25478.
