Dawid Wysakowicz commented on FLINK-9431:
-----------------------------------------

Have you considered using timed out patterns? You could express your case with:
{code:java}
Pattern.begin('A').followedBy("B").withing(Time.minutes(5)){code}
And look for the timed out patterns, rather than the matched ones. Will it work for you this way?

> Now flink cep have no support to reach a Final State upon past some time. if i use a pattern like 
> {code:java}Pattern.begin('A').notFollowedBy("B"){code}, if i want A element be emitted after 5minutes, i have no way.
> I want to introduce a timeEnd State to work with notFollowedBy to figure out with this scenior.
> It can be used like this {code:java}Pattern.begin('A').notFollowedBy("B").timeEnd("end").{code},
> [~dawidwys] [~kkl0u] Is this meaningful?
