in django

If you have multiple Redis servers set up in the replication mode, you can specify the servers either as a semicolon or comma delimited string, or as a list. While using multiple servers, write operations are performed on the first server (leader). Read operations are performed on the other servers (replicas) chosen at random:

CACHES = {
    "default": {
        "BACKEND": "django.core.cache.backends.redis.RedisCache",
        "LOCATION": [
            "redis://127.0.0.1:6379",  # leader
            "redis://127.0.0.1:6378",  # read-replica 1
            "redis://127.0.0.1:6377",  # read-replica 2
        ],
    }
}
