They can replicate queue data between RabbitMQ nodes, ensuring that queues can still run when a node breaks down. In Quorum queues, messages are written on the disk for Persistence.

This is just a dead lock, not a bug in Python. Your main process and subproces shared a single queue to communicate, but there's no guarantee when the two processes will execute - that's called a ...

Learn how to use Python’s async functions, threads, and multiprocessing capabilities to juggle tasks and improve the responsiveness of your applications.

Multiprocessing, (multi)threading ,and asynchronous programming with asyncio and Celery. Python Event-Driven architecture using RabbitMQ and pika.

Fortunately for us, the Python developers worked hard to create a multiprocessing module which has an interface that is almost identical to the threading module.

Python's "multiprocessing" module feels like threads, but actually launches processes. Many people, when they start to work with Python, are excited to hear that the language supports threading. And, ...
