+If you are using Redis, you will need to set the following variables:
+
+* `REDIS_URI`: The URI for your Redis instance.
+* `USE_REDIS`: Set to `true` to enable Redis.
+* `USE_REDIS_CLUSTER`: Set to `true` to enable Redis Cluster mode.
+* `REDIS_CA`: The path to the PEM-encoded certificate authority file for Redis TLS connections.
+* `REDIS_KEY_PREFIX`: A prefix to be added to all keys in the Redis database. Defaults to empty string if not specified.
+* `REDIS_MAX_LISTENERS`: The maximum number of event listeners allowed for the Redis client instance. It helps prevent memory leaks by limiting event listeners. If set to 0 (zero), it will be considered limitless. Defaults to 10 if not specified.
