Good to see that Redis Sentinel has alternatives. I'm working on Sentinel to provide my best solution to Redis automatic failover and monitoring but If it will not work for some of you there is something else to try.

I've never used ZooKeeper in production, so pardon my ignorance, but everytime I see a project using it I get a little bit turned off because it seems like alot of extra complexity and another SPOF. Can anyone share their experiences?

Hey Steven,

ZooKeeper is actually a proven technology for solving distributed configuration. It's widely used by Yahoo! and Netflix among other large companies. It's a proven PAXOS-like implementation, and definitely isn't a single point of failure. Check it out!

Are you sure you're not thinking of the Hadoop NameNode?

Isn't this the same idea as https://github.com/ryanlecompte/redis_failover (which may or may not be getting any traction)?

Also note that at some point there is likely to be a standard solution built into Redis itself. (The best laid plans and all that, but comments below http://news.ycombinator.com/item?id=3831295 suggest that it may come relatively soon.)

You didn't read the article. That's their repo, which they linked to in the article.
