How do I know if tables are being read?

We are using DSE Cassandra v4.8.9. I have a requirement where I need to find if the tables in Cassandra are being read using some metadata query or analyzing the logs.

We can definitely find from the application but for that we need to do code change, and we don't have cycles, so thought of considering the ways to get these details using features of DSE/Cassandra if that already available. Please advise.

It's quite simple -- just run nodetool cfstats and you will see the read count on each table. Cheers!
