    @rmetzger Can you have a look and see whether this fits into your Pojo work?

> Two issues regarding the distinct operator:
> - The distinct operator does not support {{distinct()}} with POJO datasets. I 
> think it should be possible to implement a reflection based KeySelector which 
> selects all public fields as key?
> - All other grouped operators work by {{groupBy(GROUPING).operator(...)}} 
> whereas the distinct operator does {{distinct(GROUPING)}}. I think it would 
> be more consistent to allow {{groupBy(GROUPING).distinct()}}.
