Hi! The nodes are all in different racks… except for node7 and node8!
Which is something more that makes them similar (which I didn't notice
at first), other than timeline of being added to the cluster.
About the token ring calculation… I'll retry that in NodeJS instead of
awk as a double check… yes, it checks out:
0.14603899130502265 node1 HEL1-DC2
0.14885298279986256 node2 FSN1-DC6
0.13917538352395356 node3 FSN1-DC12
0.13593194981676893 node4 FSN1-DC10
0.14054248949667470 node5 FSN1-DC11
0.14387515909570683 node7 FSN1-DC7
0.14558304396201086 node8 FSN1-DC7
(rack names are actually Hetzner datacenters, which is as accurate info
as I know… maybe those two FSN1-DC7 nodes are in different racks too)
Yeah, I'm willing to "live with it", my question was more about on the
line of "is there something I didn't understand well in Cassandra?" than
being preoccupied about the difference in usage.
All the involved keyspaces have an identical RF of:
{'class': 'NetworkTopologyStrategy', 'Hetzner': 3, 'DR': 1}
Hypothetically speaking, how would I obtain "the tokens that will
balance the ring"? Are there tools out there?
thanks in advance!
cheers,
Lapo

The load calculation always has issues so I wouldn't count on it,
although in this case it does seem to roughly line up. Are you sure your
ring calculation was accurate? It doesn't really seem to line up with
the owns % for the 33% node, and it is feasible (although unlikely) that
you could roll a node with a bunch of useless tokens and end up in this
scenario.
