About the cassandra-driver-core version.

[renyuanming]

I found that the CassandraCQLClient.java now uses cassandra-driver-core:3.x, but the new version 4.x has made lots of improvements, is there any plan to re-implement the CassandraCQLClient.java with cassandra-driver-core4.x?

It'e been a while since this comment was posted. I have a fork of YCSB with the Datastax 4.x driver that I'm planning to PR here soon (after re-writing the tests). I've used in various loads and it seems stable, feel free to use that: https://github.com/EngineersBox/YCSB
