we are currently also thinking about how to do this in the midterm,
though we don't have a test setup yet. My idea was do add one
additional node to the source cluster but put it in a different DC
as far as Cassandra is concerned. Using the network topology
replication strategy you'd assign this DC an RF of 1 for each KS.
Obviously you probably want to read and write in LOCAL_QUORUM them
to not hamper performance and you need more disk space on that
machine. But then, I think, you can just take a snapshot there and
use sstableloader to load that into your destination cluster. Since
I haven't tried this yet, I cannot tell you hoe feasible this is but
it would be nice to get some input here if the idea is at least

We have 5 node prod cluster and 3 node test cluster. Is
there a way i can take snapshot of a table in prod and load it
test cluster. The cassandra versions are same.
Even if there is a tool that can help with this it will be
If not, how do people handle scenarios where data in prod
is required in staging/test clusters for testing to make sure
things are correct ? Does the cluster size have to be same to
allow copying of relevant snapshot data etc?
