commit 9e416224b04d7d4094e5719afa4ef5bccbe48ce7 Author: Lucas Alvares Gomes <[email protected]> Date: Tue Feb 25 15:14:54 2020 +0000 [OVN] OVN DB schema update aware maintenance tasks This patch introduces a new mechanism to allow rerunning maintenance tasks upon an OVN database schema change to avoid a service restart. As an example, the "migrate_to_port_groups" maintenance task will run again when the database schema is updated. In case of a migration from an OVN version without port groups support to a version that supports it, the OVN driver will migrate the code automatically without the need of a service restart.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1864641 Title: [OVN] Run maintenance task whenever the OVN DB schema has been upgraded Status in neutron: Fix Released Bug description: When OVN DBs are upgraded (and restarted), there might be cases whenever we want to accommodate things to a new schema. In this situation we don't want to force a restart of neutron-server (or metadata agent) but instead, detect it and run whatever is needed. This can be achieved by checking the schema version via ovsdbapp [0] and comparing if it's bigger than what we had upon a reconnection to the OVN DBs.
