We are using Cassandra (3.7) counter tables in our application, and there are about 10 counter tables. The counter tables are in a separate keyspace with RF=3 (total 10 nodes). The tables are read-heavy, for each web request to the application, we read at least 20 counter values. The counter reads are very slow comparing to the other application data reads from cassandra, and sometimes the reads put extra heavy CPU load on some nodes.
Are there any tips, or best practices for increasing the performance of counter tables?
