Design Notes

Object Storage Design

Wrapping object storage with a POSIX-like interface.

Object storage is not a filesystem: it has no partial overwrite, no rename, and no directory semantics. BrewFS bridges the gap:

  • Slices turn random writes into appends that object storage handles well.
  • A transactional metadata layer provides atomic rename and directory semantics.
  • Chunk / Block layout maps file offsets to object keys deterministically.
  • Compaction and GC keep the object space from growing without bound.

The result: applications keep simple file paths, infrastructure teams keep elastic S3-compatible storage.

Agent Workload Design

Why agent workloads stress filesystems differently.
