Currently the ovn-octavia-provider driver agents are running on all controllers, all of them are connected to OVN NB / SB DB but just one of them is locked to manage the events received. After a further investigation on the hash ring manager used in neutron, a similar solution can be implemented in the driver-agent mentioned in order to take advantage of paralelism. As the hash ring manager currently implement the concept of group, we can use this field to define a set of nodes under the group 'ovn-octavia-provider' in order to not work just only the driver agents isolated from the neutron workers. The desirable solution, and given that ovn-octavia-provider already has a neutron-lib dependency, is that the hash-ring-manager functionality (currently in neutron core) is migrated to neutron-lib, where ovn-octavia-provider could take advantage of it and would not require a new dependency to talk to neutron-db, or more correctly octavia db, which would imply more profound changes. Given the special link between ovn-octavia-provider and neutron, this solution seemed to us to be the most appropriate. This way the implementation would be simple in these steps: - Removal of the current lock that only allows one driver agent to handle events. - Use the hash-ring-manager imported from neutron-lib to distribute events on the available driver agents.
