Raft consensus: leader election, log replication, and production operations
How three to seven machines agree on exactly one ordered log — leader election, AppendEntries, quorum commits, pre-vote, snapshots, and the ops discipline that keeps a Raft cluster alive in production.
- 1 Raft roles, terms, and why majority quorums prevent split brain
- 2 How Raft replicates a log entry and decides it is safe to commit
- 3 Raft leader election: timeouts, voting rules, and the four safety properties
- 4 Raft in the real world: partitions, slow disks, and client routing
- 5 Raft extensions: pre-vote, learners, snapshots, and linearizable reads
- 6 Raft in production: membership changes, Multi-Raft, and observability
- 7 Raft: multiple-choice review
- 8 Raft: free-recall review
- 9 Raft: code and log reading
- 10 Raft: build and break a cluster
