# Introduction:

`Celery` is an `asynchronous` task **queue** in **Django**, basically used for queuing time-consuming tasks. Let me give you a real world use case of `Celery`.

# Analogy:

Let’s say you have an application where you want to send a **Welcome Email** to the user after **Sign Up**, if you perform this operation synchronously with **Django**, it will be going to hold the `HTTP` **request** execution until the email is sent.

Now to solve this problem, we can transfer this task burden to a task queue such as `Celery`, so whenever a user **Sign Up** in your application, your HTTP request will continue the process, and then it will pass the task to `Celery` instance, which is running in a different server (service).

# Task Broker:

Now, `Celery` is not capable of executing those **asynchronous** task all by itself, because Celery is just a **service** running in your server.

Whenever a task comes to `Celery`, it stores the task with a **unique ID** inside a persistent storage called **Task Broker.**

Now, the job of this **Task Broker** is to assign a **task ID** to any `message` that comes, and then forward it to `Celery` for further processing.

We do not use relation databases because these are slow, on the other hand **task brokers** are **fast**, **reliable**, **concurrency** enabled.

Two very popular task brokers are **RabbitMQ** and **Redis**.

# Installation:

Installing `Celery` in a **Django** project is pretty easy:

```bash
pip install celery
```

That’s it for today, in the [next blog](https://blog.devjunction.in/set-up-celery-in-a-django-project), we will learn how to use `Celery` in a **Django** project and how to execute it **asynchronously**.
