    Perform an equijoin using block-join (aka replicate fragment join).

    Perform an equijoin using block-join (aka replicate fragment join).

    Replicate the small (left) side n times including the id of the replica in the key. On the right side, add a random integer from 0...n-1 to the key. Join using the pseudo-key and strip out the extra fields.

    Useful for skewed join keys and large datasets.
