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

[~AHeise] do you think this ticket is still valid after your optimisations 
FLINK-14044?

> Optimize AsyncWaitOperator to process more than one element per mailbox letter

>                 URL: https://issues.apache.org/jira/browse/FLINK-14097
>             Project: Flink
>          Issue Type: Sub-task
>          Components: Runtime / Task
>            Reporter: Alex
>            Priority: Minor
>
> With the changes introduced in FLINK-12958, the results (output) of 
> {{AsyncWaitOperator}} are handled via {{StreamTask}}'s mailbox letter (a 
> letter action per one input element).
> This may degrade performance of the operator: before, the emitter thread was 
> emitting elements directly to operator's output as soon as results were ready.
> This is a follow up ticket, to address this concern.
> Potential workaround can be to (non-blockingly) dequeue more ready results 
> from {{StreamElementQueue}} in one mailbox action.
> *Note:* this can also be incorporated in FLINK-14044.
