[GitHub] flink issue #3524: [FLINK-6014][checkpoint] Allow the registration of state ...

Github user shixiaogang commented on the issue:

    https://github.com/apache/flink/pull/3524
  
    @StephanEwen I have updated the PR, making the following changes:
    1. Add a method called `discardSharedStatesOnFail()` in `CompositeStateHandle`.  This method is called when the pending checkpoint fails to complete. That way, we do not need to register shared states once an acknowledge message is received.  All shared states are registered only when the pending checkpoint completes.
    2. Add `SharedStateHandle` and refactor `SharedStateRegistry` as suggested. 
    3. Both registration and unregistration of shared states now are taken place in `CompletedCheckpoint`.
    
    What do you think of these changes?
