> Currently we only check that the max number of entries in the hashmap for a 
> MapJoin surpasses a certain threshold to decide whether to execute a 
> dynamically partitioned hash join.
> We would like to factor the size of the large input that we will shuffle for 
> the dynamically partitioned hash join into the cost model too.
