> Currently aggregations work on fields of tuples, the goal of the issue is to
> extend this functionality to positions of arrays. One solution is to use an
> implementation of the KeySelector interface, however it would be a nice
> enhancement to have an API option for arrays, e.g. DataStream<int[]>
> intSream.min(0).
