Dawid Wysakowicz commented on FLINK-4641:
-----------------------------------------
In the first case I think it depends on the continuity between {{a}} and the
{{group pattern}}. 1 - is valid for skip till next(or strict), 2 - for skip
till any
In second example to which patterns applies the {{OR}}? If the {{OR}} applies
to {{c.times(1,inf)}} and {{d}} then I think there is no matches as there is
only one {{b}}. Also what continuity should I assume? The skip till any?
> Support branching CEP patterns
