Another question: would it be feasible to implement some sort of db
connection pooling?
That question keeps coming up every now and then. And with good reason because our current model doesn't scale
very well for large amounts of idle imap clients.
There a package called pgpool which seems to do the trick for postgresql only.
It would be pretty cool if we could do this ourselves though. Shouldn't be too hard :-)... All the jdbc
drivers seem to support this trick. But I don't see any C based models to study other than pgpool and
sqlrelay. And those are both using proxy processes, rather than shared memory ipc.
Perhaps a simpler approach would be to timeout database connections for idle imap clients, reestablishing them
when needed. Im not sure that would be acceptable though from a performance point of view.
