We want to add 6 more nodes into the cluster. I’m trying to see what’s better bootstapping all 6 at the same time or doing it one node at a time. I should really write a blog post on this. For safety, operators should generally bootstrap one node at a time. There are rare cases in non-vnode operation where one can safely bootstrap more than one node, but in general one should not do so. In the future in Cassandra, you will hopefully prohibited from bootstrapping more than one at a time, because it's a natural thing to do and Bad Stuff Can Happen. https://issues.apache.org/jira/browse/CASSANDRA-7069 =Rob
