>
> 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.
