Subject Re: Testing Apache Flink 0.9.0-rc1

Regarding the iteration partitioning feature, since I use it of course I
find it very useful, but it is true that it needs to be tested more
extensively and also be discussed by the community before it is added in a
release.
Moreover, given the fact that I can still use it for research purposes (I
had already cherry-picked before it is being merged to the master branch),
there is no actual reason to  put it in the next release, so that the
community has more time to discuss and decide about the feature.
Lastly, I cross checked the SAMOA application, and till now, there is still
no algorithm implemented in the SAMOA API which needs the new feature.

Faye.
