Could you build this?
No Designing a reliable, POSIX-compliant log-structured file system on top of high-latency object storage like S3 requires deep distributed storage and file system engineering.
What it would actually take: The architecture involves a FUSE user-space daemon or block device layer written in Rust/Go/C++, maintaining an in-memory metadata tree, local write-ahead log (WAL), segment cleaner/garbage collector, and distributed cache backed by S3 objects. Hard problems include snapshot isolation, lock management, POSIX atomicity over eventual consistency, write amplification, and latency masking across object store roundtrips. This requires senior storage systems engineers with expertise in log-structured filesystems (LFS) and distributed consistency models.
