> URL: https://issues.apache.org/jira/browse/FLINK-5864
> Project: Flink
> Issue Type: Bug
> Components: CEP
> Affects Versions: 1.3.0
> Reporter: Kostas Kloudas
> Assignee: Dawid Wysakowicz
> Fix For: 1.3.0
>
>
> Currently when searching for a pattern {{a,b,c}} and we have input elements
> {{a -> b1 -> b2 ->c}} where {{b1}} and {{b2}} are both valid elements for the
> position b, then instead of having an output of 2 matched patterns: {{a, b1,
> c}} and {{a, b2, c}}, we have 4, with 2 copies of each valid pattern.
> The problem is with the creation of Dewey number, cause it is not increased
> on graph branching.
