Add support for a redis failover proxy about scala-redis HOT 8 OPEN

It's definitely there in the plan. I planned to start working on the failover support once I was done with my speaking engagements at PhillyETE and QCon NY. So, now is the time I should be starting w/ it. It's definitely in the plans .. will keep you updated ..

@debasishg Have you decided on supporting a particular HA framework for Redis? I did some shopping around and (IMHO) the project I linked does the best job of what I need with the simplest parts :)

@influenza No I just had some thoughts that I would need to support a failover mechanism. scala-redis has some clustering support, but for fault tolerant demanding applications that use Redis, an automatic failover management is reuqired. I was also not aware of this gem - thanks for the pointer. I will go through it and see how it does what it does. I had some vague thoughts of trying to use Akka clustering, but it may be adding too much of a dependency. I like Zookeeper because it does what it claims and does it nicely. I will think through more on this - your suggestions are always welcome :)

Hi, came across this looking for a failover solution for Redis. I've already got Akka as part of my project. I'm curious how you could use it to solve automated failover?

It would be awesome to write a Scala client for my redis_failover project that sits on top of ZooKeeper. See http://github.com/ryanlecompte/redis_failover

I would like to again take this opportunity to express my love for your redis_failover project @ryanlecompte

Wow, thanks @influenza ! I really appreciate your comment.

FYI you can use redis-sentinel with the current library by subscribing to the +switch-master channel to handle redis failovers. @derekorgan you can use the RedisClient subscribe method providing a PartialFunction[PubSubMessage, Any] that matches on the [[com.redis.M]] case class for your callback to integrate with Akka. Note that there is about a 10 second delay between master-down and new master being selected.
