Meituan Database High Availability System

Meituan’s high‑availability database system, built on a multi‑region Raft‑group architecture, addresses rapid instance growth and stringent availability by deploying three‑node HA cores, micro‑services, and MGR clusters with AZ‑ and region‑level disaster recovery, while employing multi‑channel fault detection, weighted election, and semi‑synchronous consistency mechanisms, and outlines future moves toward decentralized proxies and fully clustered designs.
