> I propose we implement replicated join as follows-
> * Vertex 1: Loads replicated table and broadcasts it to vertex 2.
> * Vertex 2: Loads fragmented table and join it with broadcasted input from
> vertex 1.
> * New POPackage for vertex 2 that can consume a broadcast input and a file
> input needs to be implemented.
