making sure 1 copy per availability zone(rack) using EC2Snitch

2013-09-09 Thread rash aroskar
Hello, I am planning my new cassandra 1.2.5 cluster with all nodes in single region but divided among 2 availablity zones equally. I want to make sure with replication factor 2 I get 1 copy in every availability zone. As per my knowledge using placement strategy EC2Snitch should take care of this.
