[heterogenic]

One thing I'd love to see (perhaps in a future iteration?) is a way to have overlapping ranges for redundancy, instead of mirrors.

The big benefit to this is when balancing write-heavy workloads, when the slave would not be getting its share of the total load.

I believe this could be accomplished by running a second DB on each machine as a slave to the next in the cycle, and that's what I'll probably try when we scale up to needing a cluster. But having it be a supported scenario (or facilitated somehow) would make me feel much better.

(edit: Just a feature request of course, exciting to see this release! Thanks for all your hard work antirez!)
