Subject [jira] [Created] (FLINK-3181) The vertex-centric SSSP example and library method send unnecessary messages during the first superstep

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

             Summary: The vertex-centric SSSP example and library method send unnecessary
messages during the first superstep
                 Key: FLINK-3181
                 URL: https://issues.apache.org/jira/browse/FLINK-3181
             Project: Flink
          Issue Type: Improvement
          Components: Gelly
    Affects Versions: 0.10.0
            Reporter: Vasia Kalavri


The result is correct, but the current implementation has unnecessary message overhead in
the first superstep. The Messaging function should only produce messages from the source during
the first superstep. This can be fixed with a simple check of the vertex value.
