I see what you are saying. So basically take whatever existing token I have
and divide it by 2, give or take a couple of tokens?

Hello,
We just ran a repair on a keyspace using TWCS and a mixture of TTLs .This
caused a large proliferation of sstables and compactions. There is likely a
lot of entropy in this keyspace. I am trying to better understand why this
is.
I've also read that you may not want to run repairs on short

the thousands and we and up being short of a few hundred GB of disk space.

Hello! We're using TWCS and we notice that if we make changes to the
options to the window unit or size, it seems to implicitly start
recompacting all sstables. Is this indeed the case and more importantly,
does the same happen if we were to adjust the gr_grace_seconds for this
table?
Thanks!

We have a few nodes that are running out of disk capacity at the moment and
instead of adding more nodes to the cluster, we would like to add another
disk to the server and add it to the list of data directories. My question,
is, will Cassandra use the new disk for compactions on sstables that
