What is Celery architecture and how does it work?

Celery is an asynchronous task queue/job queue based on distributed message passing. It is designed to handle background tasks.

What are the main components of Celery?

The main components of Celery include the message broker, worker nodes, and the result backend. The broker handles message delivery, workers execute tasks, and the backend stores task results.

Can you explain how the message broker works?

The message broker acts as an intermediary that sends messages from the producer (your application) to the consumers (Celery workers). It ensures that tasks are queued and delivered reliably.

What are some common message brokers used with Celery?

Common message brokers used with Celery include RabbitMQ, Redis, and Amazon SQS. Each has its own strengths and use cases.

How do I set up Celery in my Python project?

To set up Celery, you need to install it via pip, configure the broker, and define your tasks in a Python module. Then, you can start the worker to process tasks.
