----------------------------------
How do you plan to pass the capacity and timeout information to the
{{RuntimeContext}} (then let it pass these parameters to the
{{RichAsyncFunction as you side}})?
> Make Queue Capacity and Timeout of AsyncWaitOperator changeable during runtime

> URL: https://issues.apache.org/jira/browse/FLINK-12691
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Konstantin Knauf
> Priority: Minor
>
> A user that I have recently been working with has the requirement to change
> the capacity and possibly the timeout during the runtime of a job.
> Conceptually, this should be possibly by just passing these parameters to the
> {{RichAsyncFunction}} via its RuntimeContext. The change of the timeout would
> only apply to future records and the change in the queue capacity would take
> effect immediately.
