That's a fair point. Does my proposal (addressed to Vish on this list a couple of minutes ago) solve this for you? In short, for the situations where you need stuff joined, we have a separate method for that. If a db driver can make this request more efficiently, that's great. If it can't, there's a slow, simple fallback. -- Soren Hansen | http://linux2go.dk/ Ubuntu Developer | http://www.ubuntu.com/ OpenStack Developer | http://www.openstack.org/ _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
