RAFT for Database Consensus at Scale

Explore a conference talk from Code BEAM America 2024 that delves into RAFT, a distributed consensus algorithm, and its implementation in database systems. Learn how the RAFT algorithm achieves consensus in distributed computing by leveraging the principle that no group can simultaneously have two simple majorities. Discover the practical applications of RAFT in database construction and gain insights into the engineering decisions behind WARaft, WhatsApp's Erlang-based implementation that supports a message database serving over 2 billion users. Throughout this 39-minute presentation, examine the technical challenges and solutions involved in scaling distributed consensus systems for massive user bases.
