Implement Raft in Rust

Consensus is one of the most important challenges in designing and building distributed systems–how to make sure multiple nodes (or agents, processes, threads, tasks, participants, etc.) in a group agree on a specific value proposed by at least one of the nodes. As an open-source distributed transactional key-value database, TiKV uses the Raft Consensus Algorithm to ensure data consistency, auto-failover, and fault tolerance. TiKV has thus far been used by almost 1000 adopters in their production environments in a wide range of industries, from e-commerce and food delivery, to fintech,…
