obstore: High-Performance Rust-Based Storage

obstore (released 2025) provides a minimal, stateless API built on Rust's object_store crate, offering superior performance for concurrent operations (up to 9x faster than Python-based alternatives).

Installation

pip install obstore

# Or with conda
conda install -c conda-forge obstore

Core Concepts

obstore uses top-level functions (not methods) and a functional API. All operations are functions like obs.get(store, path), not store.get(path).
