Description
Currently, when adding a new DC (ex: DC2) and rebuilding it from an existing DC (ex: DC1), only the closest replica is used as a "source of data".
It works but is not optimal, because in case of an RF=3 and 3 nodes cluster, only one node in DC1 is streaming the data to DC2.
To build the new DC in a reasonable time, it would be better, in that case, to stream from multiple sources, thus distributing more evenly the load.
