Subject [jira] [Commented] (FLINK-2714) Port the Flink DataSet Triangle Count example to the Gelly library

    Yes @ssaumitra, if we have the enumerator, then it's a matter of calling a `count` to
get the number of triangles. So, let's just got for `TriangleEnumerator ` in the library.
As for exposing the `Triad`, there's not need to do so. `Triad` actually extends `Tuple3`,
so I would say to simply return `DataSet<Tuple3>`.

> Currently, the Gelly library contains two methods for counting the number of triangles
in a graph: a vertex-centric version and a gather-apply-scatter version. 
> This issue proposes the addition of a third library method based on this Flink example:
> https://github.com/apache/flink/blob/master/flink-examples/flink-java-examples/src/main/java/org/apache/flink/examples/java/graph/EnumTrianglesOpt.java
> The only modification needed is an extra reduce step that takes the enumerated triangles
produced and yields a number.
