You are running it in a cluster? There are going to be a bunch of issues like this that you run into with a Redis Cluster.

I am testing this with a single instance and I think it is great however I am confused about the comment. Is this not designed to work when redis is clustered? What needs to change in order for it to work? Is this even realistic?

There are some operations that we are doing that use scripting that doesn't work in the cluster mode. That said we should fully support running in sentinel. You'd need to run all the tests against a cluster to see everything that would need to be changed for clusters.
