> The prepared statement caches in {{org.apache.cassandra.cql3.QueryProcessor}} are configured
using the formula {{Runtime.getRuntime().maxMemory() / 256}}. Sometimes applications may need
more than that. Proposal is to make that value configurable - probably also distinguish thrift
and native CQL3 queries (new applications don't need the thrift stuff).
