      Description

      Cassandra complains when using this processor to perform large numbers of changing queries. In our scenario, we are using batch statements to insert incoming data.

      INFO  [ScheduledTasks:1] 2017-10-17 16:13:35,213 QueryProcessor.java:134 - 3849 prepared statements discarded in the last minute because cache limit reached (66453504 bytes)

      In this scenario, I don't think it's feasible to use prepared statements, as the number of ? parameters is impractical. Could we instead have an option to disable prepared statements?
