-------------------------------------
Sounds like a useful extension.
> Single outstanding Async I/O operation per key

> Key: FLINK-6199
> URL: https://issues.apache.org/jira/browse/FLINK-6199
> Project: Flink
> Issue Type: Improvement
> Components: DataStream API
> Reporter: Jamie Grier
>
> I would like to propose we extend the Async I/O semantics a bit such that a
> user can guarantee a single outstanding async request per key.
> This would allow a user to order async requests per key while still achieving
> the throughput benefits of using Async I/O in the first place.
> This is essential for operations where stream order is important but we still
> need to use Async operations to interact with an external system in a
> performant way.
