> the same thing that SQLAlchemy uses Not exactly. SQLAlchemy uses greenlets as a way to "pass through" async calls through a sync layer (a classic use case), so the scope of responsibility is limited to SQLAlchemy itself. Besides, I heard that the dependency on greentlet in SQLAlchemy is not that clear (see [1](https://hachyderm.io/@zzzeek/115408550940331949), [2](https://github.com/sqlalchemy/sqlalchemy/issues/12972#issuecomment-3567958497)). The difference in your case is that greenlets are used as a way to yield to the event loop at any point in the async code. This violates the expectations of cooperative multitasking, since context switching can now occur not only at `await` points, so any user code can be affected. -- This is an automated message from the Apache Git Service.
