    Right now, there is no way to achieve this. After support for persisted results is added, this can be re-visited again. Closing for now.

> In machine learning applications it is common to split data sets into f.e. training and testing set.
> To the best of my knowledge there is at the moment no nice way in Flink to split a data set randomly into several partitions according to some ratio.
> The wished semantic would be the same as of Sparks RDD randomSplit.
