Ok I ran delta merge (then took a brief nap while waiting) and then unloaded memory (because after the merge all the partitions were partially loaded) and then reran Fernando's code. Same exactly result, it got partially loaded in memory. What I did find interesting, however is that when I first did this count with unloaded memory I had to wait a minute or so. This time when I ran the count with unloaded memory it was INSTANTANEOUS. I'm thinking how could that be if I unloaded memory? Is there cache somewhere else I'm not aware of?
