  "Currently, Apollo is developed internally at Facebook. No firm claims were made during the talk that it will be opensourced. It was mentioned as a possibility after internal development settles down." from http://java.dzone.com/articles/facebook-announces-apollo-qco...

  One of their supported storage primitives is CRDT-based, according to [1]. I, for one, am really interested to see how this works in practice. I've been quite excited about CRDTs, but haven't seen enough examples of them in the wild to get a sense of their drawbacks — for instance, how difficult it is to use them to model various processes or data structures.

  > supports anything from a minimum of three servers to thousands

  Sorry, you don't run Paxos on thousands of servers. Typical Paxos cluster sizes are 5-7. The algorithm would never converge if you did run it on thousands of servers.

  "is on-line low latency storage - in particular Flash and in-memory." "As distinct from a document oriented, or key value store, Apollo is about modifications to data structures, allowing you to represent maps, queues, trees and so on, as well as key values. "

  Sounds like Redis?
