dingbooptgampel: Why dhcp app send packet out directly instead of installing a flow to send DHCP offer packet. Because if a vm is sending huge amount of dhcp discovery packets deliberately and the packet is all packet into the controller, it will impact the local controller even crash the controller.01:06

gsagienick-ma: commented on your consistency spec, i had an idea to use a "transaction id" new table in both Neutron DB and DFDB and spot inconsistencies using that08:43
gsagieand use that as a lock08:44
gsagielet me know what you think08:44
gsagieit has some unneeded overhead but maybe its simple enough for first stage08:44
nick-maI'm also thinking of some simple method. But actually the first step I have on mind is change the scheme of lswitch, splitting it. The frequency of read/write ops on that table is really higher than any other tables. What do you think of it?08:46
nick-maEven if we fix it, the key of lswitch will always cause concurrent lock.08:47
gsagiei think its a good idea anyway08:54
gsagiethere are some parts that will need refactoring anyway08:55
gsagienow that we implement selective proactive and change the pipeline08:56

gsagienick-ma: and everyone else, feel free to look at the pipeline high level overview: https://www.slideshare.net/secret/FmRoHdDuqdKVby13:06
gsagiethis shows how i envision all the features we talked about combine in the current pipeline13:06
