[jira] [Created] (KAFKA-21026) Design JHM benchmark for "refiner"

Gavin Wang created KAFKA-21026:
----------------------------------

             Summary: Design JHM benchmark for "refiner"
                 Key: KAFKA-21026
                 URL: https://issues.apache.org/jira/browse/KAFKA-21026
             Project: Kafka
          Issue Type: Sub-task
          Components: streams
            Reporter: Gavin Wang
            Assignee: Gavin Wang


We are inserting a new “refiner” step inside the GC, which will insert “warmup tasks” if configures. The refiner runs on every heartbeat, and thus we need to carefully benchmark it.
