Are the repair times really that much of a problem? It's not like servers or erlang runtime crash that often.<br>I would think the advantages of using mnesia far outweight the disadvantages. Mnesia is much easier to scale and work with than mysql. <br>

Facebook runs on MySQL -- that's pretty scalable :)<br>
<br>
The main reason I didn't go with Mnesia for storing most data is the<br>
dets issues discussed previously on this list (specifically, the long<br>
repair times and the need for fragmentation over 4gb). I use Mnesia<br>
for storing session data though.<br>
