CFS: Scaling Metadata Service for Distributed File System via Pruned Scope of Critical Sections - Baidu's Implementation Journey
Baidu’s CFS metadata service scales to billions of files by shrinking critical sections through a lock‑free Namespace 2.0 design that confines conflicts to single shards, uses field‑level atomic primitives, and integrates the proxy into the client, delivering up to 76× throughput gains and significant latency reductions in production.
