Sorry, something seems to have happened to what I originally sent.
So this is essentially what got cut:<br>
<br>
Those controls tell me what I needed to know about the original
question. Every 3 minutes to save seems reasonable, though I'd
probably want to increase the number of allowed writes without flush
to 100,000. But while looking things up I read some things that
seemed to mean that Mnesia wanted to either hold the entire database
in memory (disc_copies) or not hold any cache (disc_only_copies).
This doesn't sound good, as what I need is a cache of active records
in RAM. I can still do this by using disc_only_copies and using it
to fill an ets table which I occasionally flush to Mnesia, but this
seems unexpectedly clumsy. Am I reading the documentation
incorrectly? I really don't expect to be able to fit the entire
table(s) into RAM.<br>
