There's two problems here, right? One of them is, did you write something where I can get enough data in memory to solve your problem without having to load a lot of stuff? And then the other problem is like, which things need to be together? So if you just naively put the chunks on different machines, it's very easy to ask a query where the chunks are in the wrong place. But there isn't really a good solution around that other than trying to minimize the amount of network latency.
