---------------------------------

             Summary: Triadic Census
                 Key: FLINK-4934
                 URL: https://issues.apache.org/jira/browse/FLINK-4934
             Project: Flink
          Issue Type: New Feature
          Components: Gelly
    Affects Versions: 1.2.0
            Reporter: Greg Hogan
            Assignee: Greg Hogan


A triad is any three vertices in a graph. An undirected graph has 4 types of triads (with 0, 1, 2, or 3 edges among the three vertices) and a directed graph has 16 types (http://vlado.fmf.uni-lj.si/pub/networks/doc/triads/triads.pdf).

This can be implemented as an analytic. The undirected implementation will use {{VertexMetrics}} and {{TriangleCount}}. The directed implementation will use {{VertexDegrees}} and {{TriangleListing}} with postprocessing.

This could be added to the {{TriangleListing}} driver in Gelly examples.
