Dong Lin commented on KAFKA-5054:
---------------------------------

[~damianguy] It seems that the PR has passed review but it is deleted without being merged. Could you double check and see if we can get it merged into 2.1.0 release?

> {{putIfAbsent}} and {{delete}} should be synchronized as they involve at least 2 operations on the underlying store and may result in inconsistent results if someone were to query via IQ
