How Version Vectors Resolve Conflicts in Multi‑Leader and Leaderless Replication

This article explains why version vectors are needed in multi‑leader and leaderless replication, describes their implementation and comparison rules, and presents practical conflict‑resolution strategies—including custom resolvers, last‑write‑wins, read‑repair, and request rejection—supported by Java pseudocode and diagrams.

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.
