Thanx,
But i'm OK with coordinator part, actually i was looking for kind of read CL to force to read from the coordinator only with no other connections to other nodes!

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 <mailto:erick.rami...@datastax.com> wrote: Yes, use a token-aware policy so the driver will pick a coordinator where the token (partition) exists.
