> This series improves load balancer performance in specific deployments
> (e.g., ovn-kubernetes) twofold:
> - patch 1/2 changes the way ARP responder flows are generated for load
> balancer VIPs, using an address set, making SB updates incremental
> and also reducing memory usage on the SB server side.
> - patch 2/2 introduces a new feature, Load_Balancer_Group, which
> simplifies load balancer configuration in large scale scenarios and
> at the same time improves performance due to the large reduction in
> database refereces between rows.
> NOTE: This series doesn't have the corresponding ovn-northd-ddlog
> changes. It wasn't clear to me what direction ovn-northd-ddlog is
> going to but if needed, I can implement the ddlog counterpart in v2
> or a follow up patch..
Thx for this improvement Dumitru :)
