I'm excited to try this. I'm trying to build something which is fairly firmly Core Data based right now but I desperately need a way to smartly cache client side because the database is growing too large. Hopefully Parse can help me out. My biggest concern is how these are stored and whether I can trust queries to be cached for very long periods of time (like until the data updates).
