---------------------------------------
okay, thanks!
> kafka-producer-perf-test should use something more realistic than empty byte
> arrays

> Key: KAFKA-2499
> URL: https://issues.apache.org/jira/browse/KAFKA-2499
> Project: Kafka
> Issue Type: Bug
> Reporter: Ben Stopford
> Assignee: Edward Ribeiro
> Labels: newbie
>
> ProducerPerformance.scala (There are two of these, one used by the shell
> script and one used by the system tests. Both exhibit this problem)
> creates messags from empty byte arrays.
> This is likely to provide unrealistically fast compression and hence
> unrealistically fast results.
> Suggest randomised bytes or more realistic sample messages are used.
> Thanks to Prabhjot Bharaj for reporting this.
