The underlying Redis client will queue up any commands if Redis is down. If you want instant errors back you can set the `enable_offline_queue` option to `false`. This allows [exp-asynccache](https://github.com/ExpressenAB/exp-asynccache) to transparently fall back to the resolve callback in such a case.
