The Opflex request_endpoint_details RPC handler is reimplemented in the apic_aim mechanism driver, using a minimal set of baked DB queries. These queries return specific individual column data rather than entire ORM objects, eliminating the sqlalchemy and DB server overhead for relationship processing. Joins are used to minimize the number of queries made to the DB server. Rather than using or emulating the dictionaries returned by Neutron's get_<resource>() methods, the RPC response is built directly from the data returned from the queries. The older RPC handler implementations remain during testing to allow performance and scalability comparison. A single implementation will eventually be selected and the others removed. Until then, the new RPC handler is enabled by setting the enable_new_rpc config variable. Change-Id: I614d5bca3f101ceab06e2fad1a59f5514b438473 |

Group Based Policy (GBP) provides declarative abstractions for achieving scalable intent-based infrastructure automation.
GBP complements the OpenStack networking model with the notion of policies that can be applied between groups of network endpoints. As users look beyond basic connectivity, richer network services with diverse implementations and network properties are naturally expressed as policies. Examples include service chaining, QoS, path properties, access control, etc.
GBP allows application administrators to express their networking requirements using a Group and a Policy Rules-Set abstraction. The specifics of policy rendering are left to the underlying pluggable policy driver.
GBP model also supports a redirect operation that makes it easy to abstract and consume complex network service chains and graphs.
Checkout the GBP wiki page for more detailed information: <https://wiki.openstack.org/wiki/GroupBasedPolicy>
The latest code is available at: <http://git.openstack.org/cgit/openstack/group-based-policy>.
GBP project management (blueprints, bugs) is done via Launchpad: <https://launchpad.net/group-based-policy>
