Yeah, you can build scalability into Mnesia, but it's not there by default. It's also dependent on what kind of data and persistence guarantees you want; if it's mostly transient data, or acceptable to lose some data in the one in a million case, Mnesia out of the box is probably fine. If you need stronger guarantees, you either have to do a lot of work, or you should investigate an alternative solution.
