Rebuild it
Implement leader election with three simulated servers and random timeouts, then add log replication.
Four prompts, in order. Each builds on the last. Write as you go; your notes stay on this device and work offline.
Challenge it
Study Figure 8. Why can't a new leader treat an old-term entry as committed just because a majority store it?
Stress it
What happens if election timeouts are shorter than message delivery time?
Compare it
Dynamo had no leader at all. What does Raft gain and lose by having one?
