2018-11-02 Thread Ben Pfaff
I was asked in an OVN meeting to send out an email talking about what we're working on to make ovn-northd and ovn-controller faster. Here's my summary. OVN is essentially a stack of compilers. At the top, the CMS dumps some configuration into the northbound database (NDBB). Then: 1.
