[jira] [Created] (FLINK-10587) Improve support of greedy/reluctant quantifiers

Dawid Wysakowicz created FLINK-10587:
----------------------------------------

             Summary: Improve support of greedy/reluctant quantifiers
                 Key: FLINK-10587
                 URL: https://issues.apache.org/jira/browse/FLINK-10587
             Project: Flink
          Issue Type: Sub-task
          Components: CEP, Table API &amp; SQL
    Affects Versions: 1.7.0
            Reporter: Dawid Wysakowicz


Right now there are limitations where greedy/reluctant quantifier can be applied:
* greedy cannot be applied for the last variable of a pattern
* optional variable cannot be reluctant

We should improve support of those cases in CEP library and enable it in SQL.
