[jira] [Created] (KAFKA-14441) Benchmark performance impact of metrics library

Jorge Esteban Quilcate Otoya created KAFKA-14441:
----------------------------------------------------

             Summary: Benchmark performance impact of metrics library
                 Key: KAFKA-14441
                 URL: https://issues.apache.org/jira/browse/KAFKA-14441
             Project: Kafka
          Issue Type: Task
          Components: metrics
            Reporter: Jorge Esteban Quilcate Otoya


While discussing KIP-864 ([https://lists.apache.org/thread/k6rh2mr7pg94935fgpqw8b5fj308f2n7]) there is a concern on how much impact there is on sampling metric values, particularly when adding metrics that record values per-record instead of per-batch.

By adding benchmarks for sampling values, there will be more confidence whether to design metrics to be exposed at a DEBUG or INFO level depending on their impact.
