Why a2wsgi

Convert WSGI app to ASGI app

The performance of uvicorn-WSGIMiddleware is higher than a2wsgi. However, when dealing with large file uploads, it is easy to cause insufficient memory uvicorn/issue#371. a2wsgi uses asyncio.run_coroutine_threadsafe to regulate the pace of reading data, thus solving this problem.

Convert ASGI app to WSGI app

The HTTP trigger of Alibaba Cloud Serverless supports the WSGI interface but not the ASGI interface, which is very useful for deploying starlette/index.py to such services.
