Design Notes
BrewFS vs JuiceFS
JuiceFS is production-first. BrewFS is Rust-first and Agent-ready.
BrewFS is not a JuiceFS clone. JuiceFS is a mature cloud-native filesystem product for production deployments, multi-protocol access, and commercial support. BrewFS focuses on a different direction: a Rust-native storage engine, transparent storage layers, and high-performance RandRW for multi-agent workspaces.
| Dimension | JuiceFS | BrewFS |
|---|---|---|
| Core direction | Production-first | Rust-first |
| Maturity | Mature productized filesystem | Early, transparent, fast-evolving |
| RandRW | Baseline in benchmark | 92% faster fully drained mixed I/O; leads 15 of 24 matched rows in the July 24, 2026 Redis + RustFS snapshot |
| Architecture | Product-oriented abstraction | Chunk / Block / Slice as first-class concepts |
| Target users | Enterprise, AI, big data, Kubernetes | Rust developers, AI infra teams, FS researchers |
