3. Step 3: Install Redis as a Celery “Broker”

Why is Celery Redis?

Celery is a task queue with focus on real-time processing, while also supporting task scheduling. Redis is a message broker. This means it handles the queue of “messages” between Django and Celery. Django is a web framework made for perfectionists with deadlines.

What is the difference between Celery and Redis?

What is Redis used for?

Redis enables you to write traditionally complex code with fewer, simpler lines. With Redis, you write fewer lines of code to store, access, and use data in your applications. The difference is that developers who use Redis can use a simple command structure as opposed to the query languages of traditional databases.

Celery is an asynchronous distributed task queue. RabbitMQ is a message broker which implements the Advanced Message Queuing Protocol (AMQP).

Is celery a message queue?

Celery is an open source asynchronous task queue or job queue which is based on distributed message passing. While it supports scheduling, its focus is on operations in real time.

Is celery same as Kafka?

Celery is an asynchronous task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well. On the other hand, Kafka is detailed as “Distributed, fault tolerant, high throughput pub-sub messaging system”.

Celery requires a solution to send and receive messages; usually, this comes in the form of a separate service called a message broker. In celery, the broker is Redis, RabbitMQ, etc who conveying the message between a client and celery.

What is Redis and Kafka?

Redis is used if you want to deliver messages instantly to the consumer and you can live up with data loss, and the amount of data to deal is less. Kafka can be used when you’re looking for reliability, high throughput, fault-tolerant, and volume of data is huge.
