Matthias J. Sax updated KAFKA-7973:
-----------------------------------
Description:
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:
