-----------------------------------

             Summary: Generate actual data with specific compression ratio in the ProducerPerformance tool.
                 Key: KAFKA-3554
                 URL: https://issues.apache.org/jira/browse/KAFKA-3554
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jiangjie Qin


Currently the ProducerPerformance always generate the payload with same bytes. This does not quite well to test the compressed data because the payload is extremely compressible no matter how big the payload is.

We can make some changes to make it more useful for compressed messages. Currently I am generating the payload containing integer from a given range. By adjusting the range of the integers, we can get different compression ratios. 

API wise, we can either let user to specify the integer range or the expected compression ratio (we will do some probing to get the corresponding range for the users)
