I am currently running some scaling test and seeing 100% CPU usage, hence asking.>Oh, no. The talk was about "OVN-controller", which is the component running on hypervisors, to translate SB data into OVS flows, and this has been implemented (although not all scenarios are incrementally processed). For ovn-northd, it runs on central node to convert data from NB to SB DB, and it is not incremental yet with incremental processing, so it is expected to see 100% CPU. There is currently a work ongoing for ovn-northd incremental processing, with DDlog, by Ben and Leonid.> Tony
