Rust Object Store

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.

See docs.rs for usage instructions

See CONTRIBUTING.md to learn how to contribute to this project.

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.

cargo build -p object_store --target wasm32-unknown-unknown

Disabling reqwest

The aws, azure, gcp, and http features each bundle a [reqwest]-based HTTP transport. To target [wasm32-wasip1] (where reqwest does not compile) or otherwise supply your own HTTP client, build against the matching *-base feature instead:

cargo build -p object_store --no-default-features --features aws-base --target wasm32-wasip1

See [Disabling reqwest] in the crate docs for full details.
