From 6d09dbfddd8b6ce8c928c4f227d4567289607e86 Mon Sep 17 00:00:00 2001 From: Robert Kukura Date: Thu, 24 Jan 2019 11:48:03 -0500 Subject: [PATCH] [AIM] New streamlined Opflex RPC handler 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_() 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.
