> (1) Currently, we always bring the entire bag into memory even though in most cases we just need to stream through it. This is very inefficient in terms of memory and CPU usage.
> (2) If we are doing multiple computations on the same group, we iterate over the bag that represents the group several times. This is very inefficient especially for spilled bags.
