Netflix uses Scryer http://techblog.netflix.com/2013/11/scryer-netflixs-predictive-auto-scaling.html for predictive and reactive autoscaling but they only refer to EC2 instances. They don't mention anything about cassandra scaling or adding and removing nodes.

I've just looked at the priam wiki and it also doesn't mention scaling. It also mentions that vnodes aren't fully supported. That's no use for me as I'm using 2.x. The other issue, rather feature of cassandra, is that adding a new node increases the load on the system so this surge would need to be taken into account.

I think I'll leave this problem for more intelligent people than me and concentrate on the application logic, which can scale by adding or removing application and front end servers.

Thanks for all your comments.
