Mnesia dB size limits

[Damir Horvat]

Hi!

I'm planing 50-70 Mbytes stored in mnesia database. I hope
this is still considered "sane" size? What are the upper limits where
system can still be called "production quality" in terms of dB speed?

Another question. Reading Joe's Robust server (bank server example), I
found this interesting:

...
[E] ->
    B = E#account.balance,
		{ok, B}
	end
...

Why not skip B and send {ok, E#account.balance} in the fist place?

Thanks, Damir.
