Commit 9d15b98261 added a method to
get objects from the DB (OVO or otherwise). This introduced a
performance problem, as seen when running "neutron port-list" with
a large number of neutron ports. On one setup with 6.5k ports, the
port-list time was on the order of several minutes. This patch makes
a minor change to this method, and imports sqlalchemy instead of just
the inspect method from that library. This reduced the same port-list
time to a low double-digit number of seconds. This follows the same
pattern that was introduced in upstream neutron (see this patch:
https://review.opendev.org/c/openstack/neutron/+/428779).

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.
