    Sorry for not responding earlier. I've missed the notification somehow.
    
    Batch exchange (the blocking intermediate results) do not work within iterations. Therefore
the optimizer never sets the exchange mode to batch within iterations currently.
    
    I think we need to suppress range partitionings within iterations for the time being.

> 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
