Hi everyone, We're being particularly hit hard across different deployments where Octavia has several SELECT .. FOR UPDATE queries which are causing load balancers to fail to provision properly. - spare_pools: This usually hits on rolling restarts of o-housekeeping as they all seem to try to capture a lock -- https://github.com/openstack/octavia/blob/73fbc05386b512aa1dd86a0ed6e8455cc6b8dc7f/octavia/controller/housekeeping/house_keeping.py#L54 - quota: This hits when provisioning a lot of load balancers in parallel. For example in cases when using Heat -- https://github.com/openstack/octavia/blob/bf3d5372b9fc670ecd08339fa989c9b738ad8d69/octavia/db/repositories.py#L565-L566 These hurt quite a lot in a busy deployment and result in a poor user experience unfortunately. We're trying to off-load Octavia to it's own database server but that is more of a "throw power at the problem" solution. I can imagine that we can probably likely look into a better/cleaner alternative that avoids this entirely? I'm happy to try and push for some of this work on our side.
