Supervisor hierarchy question

[Valentin Micic]

Would it be too crazy to atempt to provide a mnesia access module that would
use mysql or similar database for storage?
Thus, instead of using ODBC or similar one could use mnesia:activity....

BTW: I've been asked the other day why did I choose a Disney (a.k.a. Mickey
Mouse) Database for implementation of some serious data volumes. They said,
Even Ericsson is not using MNESIA... not that we have any problems, but...

How does one fight such (IMHO) unjustified argument(s)? Can anybody tell me
of any comercial application of MNESIA.

Valentin.

I am interested in helping you out, as I use postgresql from erlang and
would be interested in such an interface. Can you post the code? I can help
you test it if you'd like.
