Thrift is still present in the 2.0 branch as well as 2.1. Where did you see that it's deprecated? Let me elaborate my earlier advice. Shuffle was removed because it doesn't work for anything beyond a trivial dataset. It is definitely "more risky" than adding a new vnode enabled DC, as it does n

I believe shuffle has been removed recently. I do not recommend using it for any reason. If you really want to go vnodes, your only sane option is to add a new DC that uses vnodes and switch to it. The downside in the 2.0.x branch to using vnodes is that repairs take N times as long, where N is

Hello, I'm looking to convert our recently upgraded Cassandra cluster from a single token per node to using vnodes. We've determined that based on our data consistency and usage patterns that shuffling will be the best way to convert our live cluster. However, when following the instructions for
