-----------------------------------------------
Summary: Reduce prepared statement binding overhead for Cassandra
stress
Key: CASSANDRA-21702
URL: https://issues.apache.org/jira/browse/CASSANDRA-21702
Project: Apache Cassandra
Issue Type: Improvement
Components: Tool/stress
Reporter: Dmitry Konstantinov
Assignee: 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.
