django-redis VS Hiredis

Redis is an open-source data-structure store that can be used as a database, cache, message broker, etc. To start using Redis in your Django application, you need to first install the django-redis library. The library makes it easier to connect your Django application to Redis.

To implement caching in Django application. First, set up your Django project and application. Then install django-redis, a project by Jazzband:

django-redis

This isn't such a big deal... There are great third-party packages (i.e https://github.com/jazzband/django-redis) for whoever needs a redis cache backend in a project.

Myself, I just use good ol' memcached for all my caching needs (https://docs.djangoproject.com/en/3.2/topics/cache/#memcache...). It is rock solid and has never failed me till now!

If your example of the counter is accurate for what you want to do, it might be faster using django-redis as your cache backend and using the incr method (which adds one to a given cache key). Repeatedly inserting and deleting database records is much slower than cache operations like that would be. Or is there a way you can avoid deleting database records, and modify existing values?

hiredis

(Optional) A redis client in a programming language of your preference, I've used in Python, aioredis, in Go go-redis/redis and in C hiredis. The best documentation is with the Python guys, in my opinion of course, but the three of them are pretty straightforward, with many examples on their source code. Looking at the test folder, could also give you an idea of how to use the library.
