It is not new at all, that's exactly why I wrote the blog post, since it is an actual use case. But it is a good idea to formalize a canonical model to do it with Redis in a safe way, and to show what are the failure modes when we resort to simpler designs (like failover to slaves).

As a related aside, I'd be mildly interested in Redis having an ability to produce and produce and set UUIDs. That sort of thing might also have some utility for locking structures/synchronization primitives, though it's not the original reason I'd thought having something like that might be nice.
