Re: add new nodes in two DCs at the same time

Theoretically yes, but you should stick to 1 node at a time to keep things simple. only add multiple nodes simultaneously if you really know what you're doing and have good reason to. Also by default Cassandra will stop you from adding multiple nodes at once unless you pass certain flags.

add new nodes in two DCs at the same time

Hi, as Datastax suggests,we should only bootstrap one new node one time. but can we add new nodes in two DCs at the same time? Thanks, Peng Xiao
