Dongjin Lee created KAFKA-12219: ----------------------------------- Summary: Potential race condition in InMemoryKeyValueStore Key: KAFKA-12219 URL: https://issues.apache.org/jira/browse/KAFKA-12219 Project: Kafka Issue Type: Bug Components: streams Reporter: Dongjin Lee Assignee: Dongjin Lee
With KAFKA-8802 (included in [2.4.0 release|https://downloads.apache.org/kafka/2.4.0/RELEASE_NOTES.html]), {{ConcurrentSkipListMap}} in {{InMemoryKeyValueStore}} was reverted into {{TreeMap}} for performance issues. However, the {{synchronized}} keyword for {{reverseRange}}, {{reverseAll}} methods were omitted, leaving possibility of race condition. -- This message was sent by Atlassian Jira (v8.3.4#803005)
