    Returns true iff all distribution guarantees made by this partitioning can also be made for the other specified partitioning.

    Returns true iff all distribution guarantees made by this partitioning can also be made for the other specified partitioning. For example, two HashPartitionings are only compatible if the numPartitions of them is the same.

    Returns true iff the guarantees made by this Partitioning are sufficient to satisfy the partitioning scheme mandated by the required Distribution, i.e. the current dataset does not need to be re-partitioned for the required Distribution (it is possible that tuples within a partition need to be reorganized).
