# aiooss2 — Async client for aliyun OSS(Object Storage Service) using oss2 and aiohttp/asyncio

License: permissive · Maintenance: dormant · Downloads: 110.8K/mo

## What it is and what it does

Aiooss2 is a thin async wrapper around the Aliyun OSS (Object Storage Service) client, built on top of oss2 and aiohttp. It allows developers to perform object storage operations against Aliyun's cloud storage without blocking the event loop, making it suitable for async Python applications that need to interact with OSS. The package depends on aiohttp for HTTP handling and oss2 for the underlying OSS protocol implementation.

The package is in alpha status and has not been actively maintained since mid-2024. While it has low install friction and supports Python 3.8, 3.9, 3.10, and 3.11, the lack of recent updates and sparse documentation (marked TODO in the published description) means you should verify whether it meets your specific async use case before adopting it in production.

Use it for:

- Async Python applications that need to upload or download files from Aliyun OSS without blocking the event loop.
- Building async microservices that interact with Aliyun object storage as part of a larger async pipeline.
- Integrating Aliyun OSS operations into async web applications.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Aiooss2 provides an async client for Aliyun OSS (Object Storage Service) using aiohttp and asyncio, wrapping the oss2 library for non-blocking operations.

Yes, if you specifically need async Aliyun OSS operations and are comfortable with an alpha-stage, dormant package. The low install friction and permissive Apache-2.0 license are favorable, but the lack of recent maintenance and incomplete documentation mean you should test thoroughly and have a fallback plan. Not recommended for production use without careful evaluation.

## Install

pip install aiooss2
uv add aiooss2
poetry add aiooss2

## Installing aiooss2

Before you install: Low install friction with only two runtime dependencies (aiohttp and oss2). The package is dormant—last commit was 2024-06-17—so maintenance is minimal but the codebase appears stable.

License in practice: Licensed under Apache-2.0, a permissive open-source license that allows commercial use, modification, and distribution with minimal restrictions.

Quickstart:

pip install aiooss2

import aiooss2
# Wrap oss2 operations with aiohttp for async execution

Requires Python >=3.8; aiohttp and oss2 must be installed as runtime dependencies.

Verify before relying:

- What async operations are actually exposed by the package (documentation marked TODO in the description excerpt).
- Whether dormancy since 2024-06-17 signals abandonment risk for production use.
- Real-world performance gains from async wrapping compared to synchronous oss2 usage.
