Description of problem: With the fix for: https://github.com/ovn-org/ovn/commit/44c323a077af3709a111a6156850fd77f9302f5e we have seen a great reduction in memory and cpu usage by the SBDB. We need to enable configuration knob with ovn-k.
Since this feature changes the southbound database it will require upgrades to be handled correctly in the CNO, eg upgrade nodes before masters. Otherwise ovn-controller will pause flow changes (since it cannot understand the new database changes) until it's upgraded to a version that does understand the new DB stuff.
