Thanks Ben for sending out v7. I have few comments w.r.t to scaling. 1. In the last OVN weekly irc meeting, I had mentioned about ovn-northd-ddlog taking a lot of time in the loop. I also shared the scale test results with ddlog (https://imgur.com/JJpsMhv) and without ddlog (https://imgur.com/gmbhfoa). I was able to come up with a dirty script which you can run locally. This script creates OVN resources 250 times. As the scale increases you will notice the warning messages in the ovn-northd-ddlog log file *** timeval|WARN|Unreasonably long 1160ms poll interval (8ms user, 0ms system) *** As the test progresses the time reported in the warning also increases gradually and it reaches around 3500ms in my setup. I do not observe such warning messages with the c version of northd. Can you please test it out locally with this script - https://gist.github.com/numansiddique/1adf22cef57f6b125981b3581085694d 2. ovn-northd-ddlog is missing support for connecting to a raft cluster.
