    I would keep the `DataDistribution` in the `OutputEmitter`. 
    We can later adapt this such that we can set the `DataDistribution` at 
execution time from the broadcasted set and avoid the partition ID assignment.
    
    For now, we can simply set an Integer distribution with boundaries 
1,2,3...,n.

> The range partitioner is currently disabled. We need to implement the 
> following aspects:
> 1) Distribution information, if available, must be propagated back together 
> with the ordering property.
> 2) A generic bucket lookup structure (currently specific to PactRecord).
> Tests to re-enable after fixing this issue:
>  - TeraSortITCase
>  - GlobalSortingITCase
>  - GlobalSortingMixedOrderITCase
