Archiving capped collections - is it possible/feasible?

[Peter Bengtsson]

I like the idea of using a capped collection to store logs but what if
I want to archive them?
A cron job could periodically copy the capped collection into a non-
capped collection. (perhaps by renaming the capped collection, from
"logs_capped" to "logs_capped_to_be_archived" and create a blank one
called "logs_capped")

Are there already solutions to this problem ready made?
How do I best get on top of the size maximum so that I make sure I
archive before it reaches it's maximum?

Lastly, if having persistent logs is important to me, should I not
bother with capped collections and take the performance hit?

[Eliot Horowitz]

I think your last statement is correct.
If you want persistent logs, then you shouldn't bother with a capped collection.
Logs in capped collections are really great if you want X days of
logs, not if you want infinite logs.

Sounds about right. I might return to this in the optimization phase
if the project takes off. For now I'll just keep the indexes light.
