I meant the global whole token range which is -(2^64/2) to ((2^64) / 2 - 1)
I remember there are classes that already generate the right slices but
don't know by heart which one it was.

I have tried to retrieve the token range and slice in 4, but the response i
get for the following code is different on each node:
TokenRange[] tokenRanges =
unwrapTokenRanges(metadata.getTokenRanges(keyspaceName,
localHost)).toArray(new TokenRange[0]);
On each node, the 1024 token ranges are diff
If you have 4 Nodes with RF 4 then all data is on every node. So you can
just slice the whole token range into 4 pieces and let each node process 1
slice.
Determining local ranges also only helps if you read with CL_ONE.

Hi Frank,
You could try this
https://github.com/siddv29/cfs
I have processed 1.2 billion rows in 480 seconds with just 20 threads on
client side.
C* 3.0.9
Nodes = 6
RF = 3
Have a go at it. You might be surprised.

Hello there,
I'm running a 4 node cluster of Cassandra 3.9 with a replication factor of
4.
I want to be able to run a java process on each node only selecting a 25%
of the data on each node,
so i can process all of the data in parallel on each node.
What is the best way to do this with the java
