[jira] [Created] (FLINK-7147) Support greedy quantifier in CEP

Dian Fu created FLINK-7147:
------------------------------

             Summary: Support greedy quantifier in CEP
                 Key: FLINK-7147
                 URL: https://issues.apache.org/jira/browse/FLINK-7147
             Project: Flink
          Issue Type: Sub-task
            Reporter: Dian Fu
            Assignee: Dian Fu


Greedy quantifier will try to match the token as many times as possible. For example, for pattern {{a b* c}} (skip till next is used) and inputs {{a b1 b2 c}}, if the quantifier for {{b}} is greedy, it will only output {{a b1 b2 c}}.
