Thanks Ben for providing the background information. I spent a hour or so on Openstack Congress and my impression is that it will be evolving into a deductive engine rather than a computation engine that we need for OVN.
The obvious reason, as Russell has mentioned, is it is Python. Others reasons that I have are: * We may not want to bound to an external project. * We already have a Java engine and porting to C is straightforward. * The datalog engine in Congress may optimize in other direction not suited for OVN. -- Yusheng _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
