> 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: 0.10.2.0
>
>
> 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.
