Sorry, the second link does not point where I wanted to. Simple search for

> Key: FLINK-21308
> URL: https://issues.apache.org/jira/browse/FLINK-21308
> Project: Flink
> Issue Type: New Feature
> Components: Stateful Functions
> Reporter: Stephan Pelikan
> Priority: Major
>
> As a user I want to cancel delayed sent messages not needed any more to keep
> state clean.
> Use case:
> {quote}My use-case is processing business events of customers. Those events
> are triggered by ourself or by the customer depending of what's the current
> state of the ongoing customer's business use-case. We need to monitor
> delayed/missing business events which belong to previous events. For example:
> the customer has to confirm something we did. Depending on what it is the
> confirmation has to be within hours, days or even months. If there is a delay
> we need to know. But if the customer confirms in time we want to cleanup to
> keep the state small.
