Architecture and Design of Tencent Cloud CynosDB and CynosFS
Tencent Cloud’s CynosDB uses a shared‑storage, primary‑multiple‑replica architecture built on the user‑space distributed file system CynosFS, separating compute from elastic block storage, sinking write‑ahead logs for asynchronous replay, and employing MVCC with Raft‑replicated segments to achieve high‑availability, scalable, and cost‑effective MySQL/PostgreSQL‑compatible performance.
