> Key: CASSANDRA-21702
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21702
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Tool/stress
> Reporter: Dmitry Konstantinov

> Under high batch write load Cassandra stress burn a lot of CPU to lookup
> Codecs for bound values: 21.5% of overall CPU consumption.
> To avoid this overhead we can retrieve required codecs only for the prepared
> statement and then use explicitly them when we bind values to avoid codec
> lookup cost. It drops the overhead to 0.
