---------------------------------------
Hi [~dongjin] , thanks for your interests! It is for tracking the work that
[~spena] is working on (his PR contains the implementation but only for
internal usage, and this ticket is for eventually exposing it as public APIs).
If you like, you can take a look at his PR
(https://github.com/apache/kafka/pull/10537) and see if that matches your
thoughts too.

> We can consider adding such APIs where the underlying implementation classes
> have better optimizations than deleting the keys as get-and-delete one by one.
