> The Redis DMC directly implements Atomic DMC Client and because it implements the atomic updates using Redis transactions which don't work in a Redis cluster, it imposes a constraint that the Redis Mode cannot be set to Cluster, otherwise it is invalid. The downside is that then the Redis DMC can't be used with a Redis cluster, even in places that didn't require atomic updates like Put/Fetch DMC. We should be able to improve this.
