> As reported on this question on SO ([https://stackoverflow.com/questions/54803124/cancel-punctuator-on-kafka-streams-after-is-triggered)] if one registers a lot of punctuation one needs to track them manually if they should be cancel at some point, what can be tedious.
> It might be a good addition, to allow a `Punctuator` to cancel itself. Something like:
> {quote}void punctuate(long timestamp) {
>     // do stuff
>     if (...) {
>         this.cancel();
>     }
> }{quote}
> It's just a sketch of an idea. This ticket implies a public API change and requires to write a KIP: [https://cwiki.apache.org/confluence/display/KAFKA/Kafka+Improvement+Proposals]
