I just asked this exact same question but after maybe after reading a bit more doc than you did. You may want to read this thread: http://grokbase.com/t/cassandra/user/134j85av4x/ec2snitch-to-ec2multiregionsnitch
You also may want to read some doc. Datastax explain things quite well and update the doc regularly. Hope this will help. 2013/4/25 Daning Wang <dan...@netseer.com> > Hi All, > > We have 8 nodes cluster(replication factor is 3), about 50G data on each > node. we need to change the cluster to multi-center environment(to EC2). > the data need to have one replica on ec2. > > Here is the plan, > > - Change cluster config to mult-center. > - Add 2 or 3 nodes in another center, which is ec2. > - Change the replication factor to make data synced to other center. > > We have not done the test yet, is this doable? the main concern is that > since connection to ec2 is slow, it will take longer time to streaming > data(should be more than 100G) at the beginning. > > Anybody has done this before, please share some light, > > Thanks in advance, > > Daning > > > >
