+Rebuild operates on multiple nodes in a Scylla cluster. It streams data from a
+single source replica when rebuilding a token range. When executing the command,
+Scylla first figures out which ranges the local node (the one we want to rebuild)
+is responsible for. Then which node in the cluster contains the same ranges.
+Finally, Scylla streams the data to the local node.
