> Key: FLINK-2905
> URL: https://issues.apache.org/jira/browse/FLINK-2905
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Affects Versions: 0.10
> Reporter: Martin Junghanns
> Assignee: Martin Junghanns
> Priority: Minor
>
> Currently, the Gelly Graph supports the set operations
> {{Graph.union(otherGraph)}} and {{Graph.difference(otherGraph)}}. It would be
> nice to have a {{Graph.intersect(otherGraph)}} method, where the resulting
> graph contains all vertices and edges contained in both input graphs.
