• Django Celery Mastery ...
In today's fast-paced web development landscape, efficiently handling time-consuming and resource-intensive tasks is crucial for building high-performance applications. Django Celery, a powerful asynchronous task-processing library, provides the perfect solution to address this challenge. This comprehensive course, "Django Celery Mastery: Python Asynchronous Task Processing," is designed to empower you with the knowledge and skills necessary to harness the full potential of Django Celery and elevate your Python web applications to new heights of scalability and responsiveness.
Course Description: The course begins by guiding you through the process of setting up a fully functional Django Celery working environment. You'll learn the essentials of Django Celery, explore task producers and consumers, and gain hands-on experience building Docker containers for Django, Redis (the message broker), and Celery workers. Additionally, you'll understand the role of a results backend and create a Redis Docker container to facilitate effective task communication.
Moving forward, you'll dive deep into defining and executing Celery tasks within a Django application. You'll discover how to create and register tasks, start and manage Celery workers, and configure task routing for optimized task distribution. Advanced concepts such as task prioritization, task grouping, task chaining, task rate limits, and passing arguments and returning results from Celery tasks will be thoroughly covered. You'll also explore both synchronous and asynchronous task execution approaches and leverage the Flower monitoring tool to track and monitor Celery workers and tasks.
Handling task failures and retries is a critical aspect of asynchronous task processing, and this course provides a comprehensive introduction to this topic. You'll gain insights into common types of exceptions and errors in Celery tasks and explore various error-handling strategies. You'll implement automatic retries, handle errors in task groups and chains, and discover techniques for handling failed tasks and task timeouts. Additionally, you'll learn how to gracefully shut down tasks, clean up failed tasks, and leverage error tracking and monitoring tools such as Sentry.
Task scheduling and periodic tasks play a vital role in managing recurring tasks efficiently. In this course, you'll understand the fundamentals of task scheduling, including scheduling tasks to run at specific times or intervals. You'll explore the customization of periodic tasks, implement crontab schedules, and ensure schedule persistence in a Django application. Furthermore, you'll learn how to schedule Django custom commands using Celery Beat and monitor service status using custom event tracking and alerting mechanisms.
Throughout the course, hands-on exercises, practical examples, and real-world scenarios will enhance your learning experience and enable you to apply the concepts directly in your own projects. By the end of this course, you'll have gained mastery over Django Celery and be equipped with the skills to implement efficient asynchronous task processing in Python applications, ensuring scalability, responsiveness, and optimal resource utilization.
Whether you are a Python developer, Django developer, web application developer, software engineer, backend developer, or a technical lead/architect, this course will empower you to unlock the full potential of Django Celery and revolutionize your approach to asynchronous task processing. Don't miss this opportunity to level up your skills and supercharge your applications with the power of Celery.

Nice tutorial! I have one question: Is there a way to push messages to the queues and standalone workers will pick them automatically with no code replication? like a publisher and subscriber (consumer)? I found the implemented approach unrealistic in a big project where you need to copy your tasks to the workers
Yeah, celery can just be installed and run without the need for any other dependency or framework. I did show a basic setup nearer the start of this series. I will get some examples made up over the next weeks to add to the course and will add here on the channel of celery used in that way.
@VeryAcademy: Can you please make a tutorial on the following ---> My plan is distribute the load from PC1 from PC2, so I am trying to move my Celery Beat/Worker & Redis from PC1 to PC2.
So far, I configured my Redis over PC2 and it's working fine. I am able to access the Redis from PC1 by putting the IP of my PC2 in Redis connection information.
Upon running the celery beat celery beat -l debug and celery worker -l debug beat and worker are running, but when I schedule a task from my Django application, I am getting a message that worker got an unregistered task.
*How can I link my celery to my Django application, so it gets the tasks of my Django application and works?*
hey good stuff till now but this just doesn't feel realistic and useable copying tasks into celery worker is there a better approach can't we access the django volume inside the celeryworker and import the tasks from the volume or any other way than this.
Hi sir, can u help me? I have imported excel sheet in django database, "now i have to insert the email which should trigger the message when the specific date ends" How to do it sir?
Yeah, the standalone can execute a task without copying the Django code base into it, but it looks like it only executed tasks that have not used the ORM or table in Django like User,... If I want to use these tables in the Django database. How we can use celery for this case?
I think it’s important to remember that it isn’t a Django database it is a database. You can still interact with the db from a celery worker server.
