Session State Storage & Redis Cache Backends

1. Deep Architecture

Storing session data in standard relational databases causes a database read on every request. Offloading session storage to Redis keeps sessions in memory, serving key-value lookups in sub-millisecond times and freeing up database capacity.

3. The Code

# config/settings.py
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
SESSION_CACHE_ALIAS = "default"

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}
