Supercharging Your Django Application with Redis

Redis is the fastest win available to most Django apps: an in-memory data store you can drop in for caching, sessions, rate limiting, and task queues.

Where Redis helps

Use case	What it replaces	Win
Page/data cache	Repeated DB queries	Lower latency
Sessions	DB-backed sessions	Faster auth on every hit
Task broker	Synchronous request work	Offload with Celery/RQ

Wiring up the cache

# settings.py
CACHES = {
    "default": {
        "BACKEND": "django.core.cache.backends.redis.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379",
    }
}

Then cache an expensive view:

from django.views.decorators.cache import cache_page

@cache_page(60 * 15)  # 15 minutes
def report(request):
    ...

Measure first, cache the hot paths, and set sane TTLs — that's 80% of the value.
