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

             Summary: Add buffer/event wrapper for runtime results
                 Key: FLINK-1506
                 URL: https://issues.apache.org/jira/browse/FLINK-1506
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Runtime
    Affects Versions: master
            Reporter: Ufuk Celebi
            Priority: Minor


There is no separation between buffer or events and their metadata when adding them to an intermediate result at runtime. This was not the case up until release-0.8 and has been introduced by me with intermediate results.

I think this was a mistake and we should seperate this again using a similar wrapper as before (e.g. an Envelope).

Some of the problems of the current solution include that events are always serialized when adding them to an intermediate result and buffers are tagged to include whether they serialize a buffer or event.
