Can Multi-Leader and Leaderless Replication Achieve Linear Consistency?

This article examines why multi‑leader and leaderless replication models struggle to provide linear consistency, explores write‑conflict handling, quorum‑based NWR mechanisms, sloppy quorum and hinted‑handoff techniques, and summarizes the trade‑offs involved in achieving strong consistency across distributed data centers.

How to Achieve Linear Consistency in Single-Leader Replication: Challenges and Solutions

This article examines eventual and linear consistency in leader‑based replication, explains read‑your‑writes and shared‑data scenarios, discusses replication lag, failover trade‑offs, multi‑data‑center risks, and shows how consensus systems like ZooKeeper and etcd implement true linear consistency.

How Consensus, CAP, and BASE Shape High‑Availability Architecture

This article explains the role of consensus algorithms in achieving high‑availability through redundancy and automatic failover, clarifies distributed consistency, explores the CAP theorem and its C component, and introduces the BASE theory as a practical complement for eventual consistency in modern distributed systems.
