[jira] [Created] (KAFKA-2670) add sampling rate to MirrorMaker

Christian Tramnitz created KAFKA-2670:
-----------------------------------------

             Summary: add sampling rate to MirrorMaker
                 Key: KAFKA-2670
                 URL: https://issues.apache.org/jira/browse/KAFKA-2670
             Project: Kafka
          Issue Type: Wish
          Components: tools
            Reporter: Christian Tramnitz
            Priority: Minor


MirrorMaker could be used to copy data to different Kafka instances in different environments (i.e. from production to development or test), but often these are not at the same scale as production. A sampling rate could be introduced to MirrorMaker to define a ratio of data to copied (per topic) to downstream instances. Of course this should be 1:1 (or 100%) per default.
