Subject: Re: [PHP-DEV] persistent zval
From: smalyshev@gmail.com (Stanislav Malyshev)

Hi!

Connection pooling is persisting external resources, usually, which can
be done with little regard to zvals, since zval for resource is just a
container holding an opaque pointer. A number of extensions do
persistent connections without really persisting zvals. However, in many
cases PHP is multiprocess, so pooling becomes kind of problematic here -
it may be hard or impossible to share connections between processes, and
if you have a lot of processes, keeping connection per process can
become expensive. That is to say, connection pooling is a different can
of worms :)
