---------------------------------------
Github user dawidwys commented on the issue:
https://github.com/apache/flink/pull/4296
I think we are getting close to the final version. Good job! Still though
have two higher level comments:
- is current times().greedy() behaviour intended? For pattern `a{2, 5} b`
and sequence `a1 a2 a3 a4 b` shouldn't it return just one match: `a1 a2 a3 a4
b` Instead of three as in `testGreedyTimesRange`
- this feature should be documented in the docs. It should be also very
clearly stated there that it does not work for `GroupPatterns`
> Support greedy quantifier in CEP

> 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}}.
