> CEP within method should applied in every independent pattern
> -------------------------------------------------------------
>
> Key: FLINK-13881
> URL: https://issues.apache.org/jira/browse/FLINK-13881
> Project: Flink
> Issue Type: Improvement
> Components: Library / CEP
> Affects Versions: 1.9.0
> Reporter: YufeiLiu
> Priority: Major
>
> When I write a Pattern like this:
> {code:java}
> Pattern.begin("start").where()
> .followBy("middle0").where().within(Time.second(1))
> .followBy("middle1").where().within(Time.second(2))
> .followBy("middle2").where().within(Time.second(3))
> {code}
> the actual within time is the smallest: 1 second.
> I created a TimeCondition extends IterativeCondition, and I can get timestamp
> of current event and previous computation state, then I compare them in
> condition filter. Also make some change in NFACompiler, transform within as
> StateTransition rather than a gobal property "windowTime" of NFA.
> It could work, but I dont know should I change the implementation of within
> or create another syntax.
> [~dawidwys] Is this meaningful?
