-----------------------------------
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.
