When setting up a new (additional) data center, the documentation tells us to use "nodetool rebuild -- <old dc>" to fill up the node(s) in the new dc, and to disable auto_bootstrap.
I'm wondering if it is possible to fill the node with "auto_bootstrap=true" instead of a nodetool rebuild command. If so, how will Cassandra decide from where to stream the data? The reason I'm asking is that when using rebuild, I've learned from experience that the node immediately joins the cluster, and starts accepting reads (from other DCs) for the range it owns. But since the data is not complete yet, it can't return anything. This seems to be a dangerous side effect of this procedure, and therefore can't be used. Thanks Tom
