Hi Han, Now, I have 4000 records in logical-switch table in nb-db, only 1567 records in datapath-binding table in sb-db. The translation was broken by a duplication (2 datapath bindings point to the same logical-switch). Not sure how that happened. Anyways, I manually removed this duplication. How can I trigger ovn-northd to finish the translation for all the rest logical switches?
Thanks!

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 > > On Jul 23, 2020 4:02 PM, Han Zhou <hz...@ovn.org<mailto:hz...@ovn.org>> wrote: > > > > On Thu, Jul 23, 2020 at 11:17 AM Tony Liu > <tonyliu0...@hotmail.com<mailto:tonyliu0...@hotmail.com>> wrote: > > > > Hi, > > > > Is this implemented and released? > > https://www.slideshare.net/hanzhou1978/ovn-controller-incremental-processing > > Could anyone share an update on this? > > > > > > Thanks! > > > > Tony > > > > Yes, it was released initially in OVS/OVN 2.12 (if I remember correctly), and > there have been more improvements added gradually since then. > (The "future" part which talks about DDlog is not implemented yet.) > > Thanks, > Han > >
