Paxos Chubby * The network might drop messages between replicas * I kinda feel like “multi-“ part can be elegantly decomposed from the whole system * Also, it seems like I have been doing the distinguished proposer in the wrong way * " Paxos must force future coordinators to select that same value in order to ensure continued agreement” — How to force, I don’t quite understand * The reason why this works is subtle (and I don’t really understand) * We use a catch-up mechanism to enable lagging replicas to catch up with leading replicas * It is also to do “chaining” of multiple message in Paxos, which we don’t prepare to implement * How to test: failure injection * Our client-server also miss a proper seq number (client can implement this trivially)
