If we're doing collision checking anyway, using UUID's to being with is pointless. We're effectively reduced to a 32 bit key space and, even worse, we're not being smart enough about it to actually do without the extra DB roundtrip to check for collisions. -- 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
