I see, thanks for the replay! One more question:
I can see that multiple nodes have same sstable names for a certain keyspace / cf. I am moving 8 nodes to a 6 nodes cluster, so at some point when putting sstables in place I would overwrite files from other node. What is the best way to solve this problem? Is it safe to change sstable file name to avoid name collisions?
