But now, out of curiosity, I've tried to add a non-seed node to a new DC with auto_boostrap=true and I see that it started streaming. Did this not happen to us in previous experiments because we started adding the new DC by adding seed nodes first? So then we add non-seeds with auto_boostrap=true they didn't stream from remote DC because they believed all replicas are already available in the local DC (but the seeds are actually empty)? Could someone please explain what are the rules for actual boostrapping/streaming in the data? Regards, -- Alex
