Peter Schuller commented on CASSANDRA-3412:
-------------------------------------------
Yes, our tool auto-detects the keyspace if possible (if there is just a single
non-system keyspace) and requires a --keyspace otherwise.
If rack awareness is not enabled or the ring spaced in such a way that it
doesn't matter (again CASSANDRA-3810) there would be no need to be per-ks and
just looking at data centers would be correct and thus keyspace/RF knowledge
would not be necessary.
Maybe it could look at all keyspaces and pick the one with the highest RF, if
one doesn't choose a keyspace?
