Options

redis

Provides the Redis connection options.

namespace

Provides the Redis namespace to use, but only if redis-namespace is in use (detected with the existence of Redis::Namespace).

The namespace can also be provided as a key in the redis options if it is missing from the main options. If there is no namespace key present in either options or options[:redis], a namespace will be generated from one of the following: $REDIS_NAMESPACE, Rails.env (if in Rails), or $RACK_ENV.
