Hello Concerning the original question, I agreed with @eric_ramirez, sstableloader is transparent for token allocation number. just for info @voytek, check this post out https://thelastpickle.com/blog/2019/02/21/set-up-a-cluster-with-even-token-distribution.html You lay be interested to now if

Running 3.11.x, 4 nodes RF=3, default 256 tokens; moving to a different 4 node RF=3 cluster. I've read that 256 is not an optimal default num_tokens value, and that 32 is likely a better option. We have the "opportunity" to switch, as we're migrating environments and will likely be using
