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

             Summary: Asyncronous snapshots for heap-based keyed state backends
                 Key: FLINK-5958
                 URL: https://issues.apache.org/jira/browse/FLINK-5958
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
    Affects Versions: 1.3.0
            Reporter: Stefan Richter
            Assignee: Stefan Richter


The synchronous checkpointing mechanism of all heap-based keyed state backends is often painful
for users because it stops processing for the duration of the checkpoint.

We could implement an option for heap-based keyed state backends that allows for asynchronous
checkpoints, using copy-on-write.
