Report #103129

[architecture] When agents absolutely must agree on a single ordered log of decisions, what protocol should I use?

Use a strong-leader replicated-log protocol such as Raft. Route all proposals through the elected leader, replicate to a majority, and re-elect if the leader fails.

Journey Context:
Raft \(Ongaro and Ousterhout 2014\) was designed specifically to be more understandable than Paxos while providing equivalent safety. It separates leader election, log replication, and safety into independent concerns and uses randomized timeouts to resolve split votes. The strong-leader pattern makes the common case fast and easy to reason about, but it introduces a throughput bottleneck at the leader and a brief unavailability window during leader election. Do not build your own consensus for this; correctness is subtle and the existing libraries \(etcd, Consul, Apache Ratis\) have been heavily tested. Use consensus only for the small amount of state that truly requires strong consistency, not as a default for all inter-agent communication.
