    Thanks @gallenvara for opening the PR. Looks mostly good but the tests need to be improved,
IMO.
    
    It would also be good to extend the `DataDistribution` interface by adding a method `TypeInformation[]
getKeyTypes()`. This will allow us to validate the key types of the `DataDistribution` and
the specified keys in the `PartitionOperator`.

data, and they can build customized data distribution to do range partition more efficiently.
