Introduction to OVSDB Query Optimizer and Key-Value interface

Speaker: Dmitry Yusupov, NVIDIA Slides: https://ovsorbit.org/episode-72-slides.pdf OVS Orbit episode: https://ovsorbit.org/#e72 OVSDB (management protocol RFC 7047) is a fundamental building block of modern SDN architecture based on OVN/OVS. OVSDB is the key component that is responsible for efficient scalability of large deployments, such as 1000+ node Kubernetes clusters when CNI function is OVN based. OVSDB was originally designed to store configuration for Open vSwitch daemon, however, it was later extended to be part of OVN architecture, with added RAFT clustering support and improved scale-out capabilities, such as efficient scale-out caches. This talk brings a question of scaling up OVSDB with introduction of OVSDB Query Optimizer using primary and alternate key indexing. We will be also looking at OVSDB with Query Optimizer as high-performance Key-Value API interface and compare it to ETCD.
