             Summary: ProducerPerformance.java : Add support to supply custom message payloads.
                 Key: KAFKA-4432
                 URL: https://issues.apache.org/jira/browse/KAFKA-4432
             Project: Kafka
          Issue Type: Improvement
            Reporter: Sandesh Karkera
            Priority: Minor
             Fix For: 0.10.0.2


Currently, kafka-producer-perf-test.sh does not support supplying custom payloads to read messages from. The payload generated is a static payload which is not very useful when testing features like compression. 

We can improve the ProducerPerformance.java to accept a "--payload-file" and "--payload-delimiter"(optional) parameters instead of "--record-size". This will enable to user to run performance tests using custom payloads. 

Before every send, we'll pick up a random payload from the payload-file provided. 

--payload-file: Will consists of messages delimited by "--payload-delimiter". 
--payload-delimiter: Takes a default value of "\n" if not specified.
