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

             Summary: Extend JSON plan dump to contain channel info
                 Key: FLINK-2686
                 URL: https://issues.apache.org/jira/browse/FLINK-2686
             Project: Flink
          Issue Type: Improvement
          Components: Optimizer
    Affects Versions: master
            Reporter: Ufuk Celebi
            Priority: Minor


The execution plan JSON (via {{env.getExecutionPlan()}}) contains no information about the data exchange mode of the used channels.

I think this would be super helpful while debugging problems like FLINK-2685. The channel types should also be considered in the plan rendering, but that's a separate issue.
