> After the changes from [FLINK-6048], it would make sense to parallelize the execution of the `RunnableFuture`s of (async) snapshot in `AsyncCheckpointRunnable`. Currently, `AsyncCheckpointRunnable` is a thread that runs parallel, but executes each snapshot sequentially. The reason is, that previously only keyed state backends had support for async snapshots.
