> When a vertex changes its parallelism, consumer vertices may need to respond to it. 1-1 consumer vertices would need to change their parallelism to match. Scatter-gather consumers dont need to change. 
> Currently, the tez dag code has special cased this for 1-1 edge which is fine for now but does not work with custom edges.
