@Thibaut Britz
Caveat:Using simple strategy.
This works because cassandra scans data at startup and then serves
what it finds. For a join for example you can rsync all the data from
the node below/to the right of where the new node is joining. Then
join without bootstrap then cleanup both nodes. (also you have to
shutdown the first node so you do not have a lost write scenario in
the time between rsync and new node startup)


rsync all data from node to left/right= ..
Wouldn't that mean that you need 2x the data to recover...= ?
