Obstore is a new stateless object store that skips fsspec-style caching and keeps its API tight and predictable across S3, GCS, and Azure. Sync and async both work. Under the hood? Fast, zero-copy Rust–Python interop. And on small concurrent async GETs, it reportedly crushes S3FS with up to 9x better throughput.

System shift: Stateless APIs are trending—for good reason. Less hidden state means clearer, saner access patterns in distributed systems.
