Django - Celery and Background Tasks

If you invoke a Celery task function directly like send_notification() instead of send_notification.delay(), what is the outcome?

AThe task runs immediately and synchronously in the current process

BThe task is queued and executed asynchronously by a worker

CAn error is raised because delay() is required

DThe task is scheduled but never executed

Step-by-Step Solution

Solution:

Step 1: Understand direct call behavior
Calling the task function directly executes it immediately in the current process, not asynchronously.
Step 2: Contrast with delay()
Using delay() sends the task to the queue for asynchronous execution by workers.
Final Answer:
The task runs immediately and synchronously in the current process -> Option A
Quick Check:
Direct call runs task synchronously [OK]

Quick Trick: Direct calls run tasks synchronously, use .delay() for async [OK]
