    Thanks for the review in advance, @fhueske . Something i want to mention 
here is that, the range partitioner implementation in this PR follow the 
existed partitioner design pattern, which in my personal view, is not well 
designed by the principle of object-oriented programing, the parameters of 
different partitioners are passed through Flink all together, and all 
partitioners logic mixed in OutputEmitter, i'm not very satisfied with the 
implementation in this PR actually. I think we need refactor the partitioner as 
a followup work, but this should not block this PR. Range partitioner is a 
little different from other partitioners, with it enabled, we could have a 
better overview about how to design the abstraction of partitioner. The 
refactor should require a design doc and fully discussed in community, what do 
you think about this?

> 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
