Is it possible to start with having only 1 replica or no replication ? Right now, my data is not that important so I want to use as much disk space as I can, thus don't need replication. In future when I have more servers or disks, I would want 3 or 2 or 4 replicas and want to switch to that. Is that possible ?

If so, do I just use set_replicas 1 and rebalance and then in future use same command with 3 replicas and rebalance ?

Yes, it is possible. Try with single replica now and rebalance it, later you can also try with 3 replicas and following the same steps. :)

You don't use set_replicas initially, but specify the replicas in create subcommand. But later you can change the number of replicas using set_replicas as you expect.

Note that you must guess the correct partition power for the future expansion. It cannot be changed.
