You can add table fragments to overcome this limitation. However, keep in mind that Mnesia isn't designed to store very large datasets. It works best with data sets that fit in RAM.

But RAM can be substantially larger than 4GB these days.

True. However, the reason Mnesia is better suited for in-RAM data sets is that its disk-only storage engine, dets, requires a potentially long repair process if the VM crashes and a dets table isn't closed properly. This could keep your table inaccessible for a while after you restart the VM.

Heh, the same principal restricting the mnesia database to 4 gigs on a 32 bit system is restricting the ram size to 4 gigs on a 32 bit system. (Some OS/Hardware magic can get around this but for the most systems this is true).
