token-aware policy doesn't work for token range queries (at least in the Java driver 3.x). You need to force the driver to do the reading using a specific token as a routing key. Here is Java implementation of the token range scanning algorithm that Spark uses: https://github.com/alexott/cassandra-dse-playground/blob/master/driver-1.x/src/main/java/com/datastax/alexott/demos/TokenRangesScan.java
I'm not aware if Python driver is able to set routing key explicitly, but whitelist policy should help On Wed, Nov 11, 2020 at 7:03 AM Erick Ramirez <erick.rami...@datastax.com> wrote: > Yes, use a token-aware policy so the driver will pick a coordinator where > the token (partition) exists.
