Rust Object Store
March 19, 2026 ยท View on GitHub
A focused, easy to use, idiomatic, high performance, async object
store library for interacting with object stores.
Using this crate, the same binary and code can easily run in multiple clouds and local test environments, via a simple runtime configuration change. Supported object stores include:
- AWS S3
- Azure Blob Storage
- Google Cloud Storage
- Local files
- Memory
- HTTP/WebDAV Storage
- Custom implementations
Originally developed by InfluxData and later donated to Apache Arrow.

Support for wasm32-unknown-unknown target
It's possible to build object_store for the wasm32-unknown-unknown target, however the cloud storage features aws, azure, gcp, and http are not supported.
