[jira] [Updated] (KAFKA-13939) Memory Leak When Logging Is Disabled In InMemoryTimeOrderedKeyValueBuffer
[ https://issues.apache.org/jira/browse/KAFKA-13939?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jackson Newhouse updated KAFKA-13939:
-------------------------------------
Description: 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. (was: 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. )
