> Currently partitions masks must be defined as a binary mask. As a result the number of partitions must be a power of 2, otherwise the distribution of tuples will be uneven. If we support the modulus operation instead of a binary mask, we could support an even distribution of tuples to a non-power of 2 number of partitions.
