[jira] [Created] (FLINK-11667) Add Synchronous Checkpoint handling in StreamTask

Kostas Kloudas created FLINK-11667:
--------------------------------------

             Summary: Add Synchronous Checkpoint handling in StreamTask
                 Key: FLINK-11667
                 URL: https://issues.apache.org/jira/browse/FLINK-11667
             Project: Flink
          Issue Type: Sub-task
          Components: State Backends, Checkpointing
            Reporter: Kostas Kloudas
            Assignee: Kostas Kloudas


This is the basic building block for the SUSPEND/TERMINATE functionality. 

In case of a synchronous checkpoint barrier, the checkpointing thread will block (without holding the checkpoint lock) until the {{notifyCheckpointComplete}} is executed successfully. This  will allow the checkpoint to be considered successful ONLY when also the {{notifyCheckpointComplete}} is successfully executed.
