> Unable to cancel a DoFn Timer
> -----------------------------

> Key: BEAM-7167
> URL: https://issues.apache.org/jira/browse/BEAM-7167
> Project: Beam
> Issue Type: Bug
> Components: beam-model
> Affects Versions: 2.12.0
> Reporter: Neil Kolban
> Assignee: Pablo Estrada
> Priority: Minor
>
> The following was raised on
> [Stackoverflow|[https://stackoverflow.com/questions/55875832/how-to-cancel-unset-a-dofn-defined-timer]]:
>
> Having read [Timely (and Stateful) Processing with Apache
> Beam|https://beam.apache.org/blog/2017/08/28/timely-processing.html] and
> looked at the JavaDoc for a
> [Timer|https://beam.apache.org/releases/javadoc/2.12.0/org/apache/beam/sdk/state/Timer.html],
> I have successfully setup a timer to be fired. However, I am missing how to
> request that a timer be cancelled before it has fired. Is this a semantic
> that is possible / allowable in Beam architecture?
> My back-story is that I wish to register a timer to fire a callback if
> something has not occurred ... but if it HAS occurred prior to the timer
> firing, then I wish to cancel the timer from being fired.
