A technical overview of Raft, with Diego Ongaro

Love computer science, algorithms, and systems? This meetup is just for you!

We've invited Diego Ongaro, author of the Raft Consensus Algorithm (used by CoreOS and other large open source projects), to talk about his consensus algorithm, Raft, and to show a sneak peek of his upcoming project, LogCabin.


Consensus is a fundamental building block for fault-tolerant systems, but it's poorly understood. We struggled to build a real system with Paxos, the most widely used consensus algorithm today. As a result, we developed Raft to be easier to understand. In this talk, I'll give an overview of how Raft works. More info on Raft can be found at


Diego recently completed his PhD with John Ousterhout at Stanford.During his PhD, he worked on RAMCloud (a 5-10 microsecond RTTkey-value store), Raft, and LogCabin (a coordination service builtwith Raft). He's lately been continuing development on LogCabin as an independent contractor.

    Special thanks to Diego for an awesome presentation on Raft and LogCabin, and hat tip to everyone who gave lightning talks! We'll be editing the video and publishing it sometime in the next week. If you shared a lightning talk, please share your project here on the event page so people can link to it. See you at the next meetup with Armon Dadgar, creator of Consul and co-founder of HashiCorp.

      Looking forward to seeing the video. I assume it will be posted on your Youtube channel? It's great you take pains to record video and I just want you to know that others outside of the Valley appreciate the effort.

      Thanks @Vincent! We usually take about a week at least to edit the video with slides so that you can follow along. Will keep you posted!

    This sounds awesome! I'll be in Mountain View that day but will try to stop by if I get back into the city in time.
