Django Celery

This is a simple django application that is meant to demonstrate the use of celery in a Django application.

The key uses of celery include:

• Offloading long-running tasks: Celery can execute tasks that take long to execute while the user continues to use the application.
• Celery can aid in sending emails asynchronously in the background if sending emails is one of the functions required in the application.
• Celery can be used to schedule and run period tasks.
• Distributed computing: In cases where the application requires handling large amount of data, celery can be used to distribute tasks across several workers to speed up the processing time.
• Celery can be used to route tasks to different queues based ont eh type of task and/or priority of the task.

Key Components

Message Provider: Django

* Provides the instructions/tasks that are to be executed

Message Broker: Redis

* Receives task from the message provider, stores and then posts it in a queue. 
* The broker delivers the task to the celery worker for processing. 
* Redis is known for quick and write provision.

Celery Worker: Celery

* Responsible for executing the task. 
* Play a crucial role in distributed task processing. 
* The worker retrieves the task from message queue and performs the desired operation. 
* Some tasks can be sent back to the message provider for further processing. 
* They are designed to be highly available and fault tolerant.
