--------------------------------------------
Summary: Improve accuracy of ProducerPerformance target throughput
Key: KAFKA-1807
URL: https://issues.apache.org/jira/browse/KAFKA-1807
Project: Kafka
Issue Type: Improvement
Components: clients, tools
Affects Versions: 0.8.1.1
Reporter: Ewen Cheslack-Postava
Assignee: Ewen Cheslack-Postava
Priority: Minor
Fix For: 0.8.3
The code in ProducerPerformance that tries to match a target throughput is very
inaccurate because it doesn't account for time spent sending messages. Since we
have to get the current time to timestamp the messages, we can be much more
accurate by computing the current rate over the entire run and only add to the
sleep deficit if we're above the target rate.
