Django Server
=============

Install Redis
-------------

`Redis <https://redis.io>`_ improves performance by storing frequently accessed data in memory, reducing database queries. It is used in Django for caching, session management, and as a message broker to improve performance and enable real-time features. To speed up cache access, the faster in-memory cache Redis is used.

Install Redis:

.. code::

    sudo apt-get install redis-server

Ensure that the Redis server is running:

.. code::

    sudo service redis-server start
