Question 1

What is the main role of Celery in a Django application?

Accepted Answer

Celery is a distributed asynchronous task queue that allows executing long-running or resource-intensive operations in the background, without blocking HTTP requests. This improves user experience by making the application more responsive, particularly for sending emails, image processing, or intensive computations.

Question 2

Which Celery component is responsible for storing pending task messages?

Accepted Answer

The message broker (like Redis or RabbitMQ) is the central component that stores task messages pending execution. It acts as an intermediary between the task producer (Django) and the Celery workers that consume and execute these tasks.

Question 3

How to define a basic Celery task in a Django application?

Accepted Answer

A Celery task is defined by using the @shared_task or @app.task decorator on a Python function. The @shared_task decorator is preferred as it allows reusing the task across different applications without depending on a specific Celery instance.
