What it means is that if you override the weigh_objects() method of the BaseWeigher class, you can make a single call to Cyborg with a list of all the hosts. That call could then create a list of weights for all the hosts and return that. So if you have 100 hosts, you don’t need to make 100 calls to Cyborg; only 1. -- Ed Leafe __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
