Message Queues cookbook

My FastAPI endpoint still blocks on the slow part, and BackgroundTasks disappears the moment the process restarts.

My worker just picked up a job when I killed it, and the job is gone: no error, no retry, nothing.

Still guest and guest. I never got around to changing it.

One bad message keeps failing and RabbitMQ keeps redelivering it, and it's sitting in front of every message that came in after it.

Every service I add ends up with its own queue wired straight to the producer, and the producer now has to know about all of them.

A webhook consumer of mine crashed right after writing to the database but before acking the message, and it got redelivered and processed twice.

Does RabbitMQ actually have my message, or did my backend just lie to the customer?

Two events about the same order arrived at my consumer out of order, and I don't know why since I published them one after another.

My team wants a new event stream and everyone has a different opinion on whether it belongs on RabbitMQ or on Kafka.

I added a field to an event my service publishes, and three days later a teammate found out a downstream dashboard had silently stopped updating.
