README
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.
