  8. def cogroup[V2, R](right: TypedPipe[(K, V2)])(joiner: (K, V, Iterable[V2]) ⇒ Iterator[R]): SketchJoined[K, V, V2, R]

    Like a hashJoin, this joiner does not see all the values V at one time, only one at a time.

    Like a hashJoin, this joiner does not see all the values V at one time, only one at a time. This is sufficient to implement join and leftJoin
