[jira] [Created] (KAFKA-19470) Avoid creating loggers repeatedly to affect the performance of request processing

terrytlu created KAFKA-19470:
--------------------------------

             Summary: Avoid creating loggers repeatedly to affect the performance of request processing
                 Key: KAFKA-19470
                 URL: https://issues.apache.org/jira/browse/KAFKA-19470
             Project: Kafka
          Issue Type: Improvement
          Components: core
    Affects Versions: 2.8.2
            Reporter: terrytlu
         Attachments: image-2025-07-04-19-05-51-900.png

We see that the broker has a performance bottleneck when processing requests. The CPU profiler is as follows:

!image-2025-07-04-19-05-51-900.png|width=1734,height=796!

seen in KAFKA-15141, the corresponding classes IncrementalFetchContext/DelayedProduce/SessionlessFetchContext have been processed, but I think a better approach should be to optimize the trait Logging, we can introduce a static Map object to cache the duplicate loggers
