[jira] [Created] (FLINK-5924) Support asynchronous checkpointing of operator state

Till Rohrmann created FLINK-5924:
------------------------------------

             Summary: Support asynchronous checkpointing of operator state
                 Key: FLINK-5924
                 URL: https://issues.apache.org/jira/browse/FLINK-5924
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
    Affects Versions: 1.3.0
            Reporter: Till Rohrmann


It would be great if we could checkpoint operator state asynchronously. That way we would not risk blocking the processing of elements due to a file system write quota, for example.

Being able to asynchronously checkpoint operator state entails that we can obtain a copy of the original state in case of a concurrent write operation.
