YufeiLiu created FLINK-13881:
--------------------------------
Summary: 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
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?
