terrytlu updated KAFKA-19470:
-----------------------------
Description:
We see that the broker has a performance bottleneck when processing requests in
kafka 2.8.2 version. The CPU profiler is as follows:
!image-2025-07-04-19-05-51-900.png|width=1065,height=489!
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
