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.

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
