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

             Summary: Execution statistics for vertex-centric iterations
                 Key: FLINK-1759
                 URL: https://issues.apache.org/jira/browse/FLINK-1759
             Project: Flink
          Issue Type: Improvement
          Components: Gelly
    Affects Versions: 0.9
            Reporter: Vasia Kalavri
            Priority: Minor


It would be nice to add an option for gathering execution statistics from VertexCentricIteration.

In particular, the following metrics could be useful:
- total number of supersteps
- number of messages sent (total / per superstep)
- bytes of messages exchanged (total / per superstep)
- execution time (total / per superstep)
