aitozi created FLINK-9431:
-----------------------------

             Summary: Introduce TimeEnd State to flink cep
                 Key: FLINK-9431
                 URL: https://issues.apache.org/jira/browse/FLINK-9431
             Project: Flink
          Issue Type: Improvement
          Components: CEP
    Affects Versions: 1.4.2
            Reporter: aitozi
            Assignee: aitozi


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?
