Queues - The Secret Sauce
summary
Shows concrete patterns using asyncio queues to serialize access to a risky resource by confining the connection object inside a single handler task, with request/response tuples and a single-consumer loop. Demonstrates an event bus that fans out a central event queue into per-subscriber queues, uses a shutdown sentinel for graceful exit, and recommends logging to trace origins. Notes using an executor for blocking libs like SQLAlchemy or requests when needed.
