Github user rmetzger commented on the pull request: https://github.com/apache/flink/pull/393#issuecomment-74712141 The pull request now also contains changes to fix two classloading issues with the newly added `ExecutionConfig`. Also, it fixes the Web interface for YARN. I would like to merge this change soon. I've tested the code on extensively on a cluster and it seems to be stable. I'm still working on the performance numbers. The results I've got so far are the following: Scale Factor 1 (lineitem only) Pojo: 20 Kryo (with key selectors): 13 Avro (with key selectors): 10, 15, 13 Scale factor 100: Pojo: 1634, I'll update the comment to complete it.
