- Raft is a consensus algorithm for distributed systems ensuring safe and consistent data replication.
- Analogized with Mean Girls: leader-follower dynamics (Queen Bee and Plastics) illustrate consensus and quorum.
- Quorum requires majority approval; in a cluster of 3, 2 votes are needed to commit changes.
- Leader election occurs when a leader fails to send heartbeats; a new candidate is voted in.
- Clients send requests to the Raft leader, who replicates data to followers before committing.
