Understanding Paxos and Consensus Algorithms in Distributed Systems

Understanding Paxos and other consensus algorithms, this article explains how crash‑fault‑tolerant protocols like Paxos, Raft, and ZAB achieve sequential consistency through two‑phase voting, contrasts them with Byzantine‑fault‑tolerant methods, and details Multi‑Paxos optimizations, leader election, and practical trade‑offs for distributed systems.

Understanding the Paxos Consensus Algorithm Through a Three Kingdoms Analogy

This article explains the Paxos consensus algorithm by mapping its roles and phases to characters and events from the Three Kingdoms era, detailing the Prepare and Accept stages, proposal numbering, and how proposers, acceptors, and learners achieve fault‑tolerant agreement in distributed systems.

Impact of High Network Latency on MySQL Group Replication Performance

An experiment with a three‑node MySQL Group Replication (MGR) cluster shows that even when flow control is disabled, adding significant network latency to a single node reduces overall throughput, because MGR’s multi‑paxos protocol makes the delayed node a performance bottleneck during its turn as leader.
