----------------------------------
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.
