The documentation about sstableloader is a bit unclear about WHERE this utility should be executed
On the source node (who has the data) OR the target node (who receives the data)?
In both cases, does this imply ALL nodes in a cluster?
Q1. For example. The source cluster has 10 nodes (5 Keypaces, each keyspace has 20 tables). The target cluster has 15 nodes. On which nodes should we run sstableloader?
Q2. Is it possible to use nodetool rebuild to achieve the same result than sstableloader?
