The OVSDB Query Optimizer and Key-Value Interface, with Dmitry Yusupov from NVIDIA

Dmitry Yusupov submitted a talk to the Open vSwitch 2020 Fall Conference

that we weren't able to fit into the schedule. This podcast, recorded in

December 2020, is based on the material that Dmitry presented in a video available on YouTube.

The slides for Dmitry's talk are also

available.

The abstract for this talk is:

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.
