Async PyMongo with Greenlet

June 12, 2023

Proposal

Use greenletio to add asyncio support in PyMongo, with minimal changes to existing classes.

Background

The reason that Motor is not "truly asynchronous" is that we have blocking calls in PyMongo that do not enable cooperative multitasking. These include acquiring thread locks and socket i/o. Even if we were to use non-blocking versions of these, the event loop would still be blocked.

The previous proposal required rewriting the entirety of PyMongo to be asyncio-friendly, and gave a small performance hit for synchronous code, especially noticeable for small documents.
