Distributed Consensus in 15 Minutes!
Tue, 23 April
Getting two computers to agree on a value seems easy. One computer thinks of a value and tells the other. But in the real world where many values are shared, concurrency and race conditions are plentiful, and failures occur at inconvenient points, getting two (or more) computers to agree on a value is really hard work. In this talk we will discuss Raft, which is a a humane protocol for dealing with all these challenges. Raft is designed for simplicity to disallow tricky edge cases, and with a simple extension we developed, can be made to work over the WAN.
