Unintentionally we have lost (terminated in AWS console for a manual error) 5/12 Cassandra nodes from a AWS datacenter. So we are trying to get new nodes to replace them after "nodetool removenode" on dead nodes.
Can I add new servers to existing datacenter with "auto_bootstrap: false" and run nodetool rebuild on new nodes?
And Can I run nodetool rebuild on multiple nodes at a time? if yes, what could be the downside of it?
Thanks in Advance!
