> Issue Type: Improvement
> Components: API / DataSet

> This is only an API problem, I hope.
> I also know, that this is potentially a very bad idea because everything must
> be sorted on one node. In some cases, such as sorted first-n this would make
> sense, though, since there we use a combiner.
