I apologize if this is a stupid question, but I was under the
impression that using mnesia w/ disc_copies meant that your entire
data set has to fit in RAM? For most large-scale datasets, even with a
lot of RAM, that makes mnesia not really desirable as you'd get a low
density of data-to-node (i.e. I can put  1 TB of disk in a node but
probably can't afford that much RAM).
