Raft Trend 2026

Raft is a lightweight, open-source consensus algorithm that manages a replicated log across distributed systems. It ensures fault tolerance by electing a leader to coordinate data replication, simplifying complex state machine replication for databases and clusters. Developers building scalable, reliable infrastructure—such as key-value stores or microservices—benefit from its easy-to-understand design, which prioritizes clarity and operational safety over performance trade-offs.
