WebApr 27, 2024 · The key difference between Paxos and Raft algorithms is that Raft allows only the best updated nodes to take on the role of the leader, while with the Paxos algorithm it can be any node [23] . The ... WebRaft is a consensus algorithm for managing a replicated log. It produces a result equivalent to (multi-)Paxos, and it is as efficient as Paxos, but its structure is different from Paxos; this makes Raft more understandable than Paxos and also provides a better foundation for building practical systems.

WebRaft better than questions about Paxos. Raft is similar in many ways to existing consensus al-gorithms (most notably, Oki and Liskov’s Viewstamped Replication [29, 22]), but it has several novelfeatures: • Strong leader: Raft uses a stronger form of leader-ship than other consensus algorithms. For example, WebMay 1, 2024 · In Raft, a new leader must be a fully caught-up replica with the longest log, while Multi-Paxos can pick any node as a leader and recover missing log entries. The authors argue that this Raft behavior is good for efficiency — the new leader can start quickly since it does not need to learn any missing entries.
WebDec 4, 2014 · Paxos actually solves the more general problem of consensus, hence, it can be used to implement transaction commit as well. In comparison to 2PC it requires more messages, but it is resilient to manager failures.
