Stefan Richter commented on FLINK-5924:
---------------------------------------
Was this issue about the raw (stream-written) or managed (backend) operator
state? In the second case, I would close this.
> 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.
