Build a User-Space File System with FUSE for a Storage Startup
Overview
What this challenge is about.
Build a FUSE driver (your choice of Rust + fuser crate or Go + bazil/fuse) that proxies POSIX operations to the startup's existing S3-compatible REST API (mock provided). Support open, read, write, mkdir, readdir, getattr, and unlink. Benchmark on a 10-GB working set against an NFS baseline: throughput, latency, metadata-op throughput. Honestly identify the worst-case workload (likely small-file metadata-heavy). Deliver the source, a docker-compose-based reproduction, a benchmark report, and a 4-page go/no-go memo for the CTO.
The Brief
What you'll do, and what you'll demonstrate.
Build a working FUSE driver over an S3-compatible API and honestly assess whether it's production-viable for backup workloads.
Earning criteria — what you'll demonstrate
- Understand the VFS layer and how FUSE proxies it to user space
- Implement correct POSIX semantics for read/write/metadata operations
- Benchmark file-system workloads with reproducible setup
- Make a defensible go/no-go technical recommendation
