> If `loggingEnabled` is false, the `dirtyKeys` Set is not cleared within `flush()`, see [https://github.com/apache/kafka/blob/3.2/streams/src/main/java/org/apache/kafka/streams/state/internals/InMemoryTimeOrderedKeyValueBuffer.java#L262.] However, dirtyKeys is still written to in the loop within `evictWhile`. This causes dirtyKeys to continuously grow for the life of the buffer.
