Multi-Paxos vs Raft Consensus Mechanics

What are the core architectural differences in leader invariants and log repair between Multi-Paxos and Raft?

Stack: THE CHAOS STACK →Staff (L6-L7)architecture-pattern

⚡THE SHORT ANSWER

Raft enforces a strong leader invariant where logs flow unidirectionally to simplify formal correctness; Multi-Paxos allows out-of-order log entries and uncoordinated commits.
