It would be great if we could datalevin kv store could implement IPersistentMap or java.util.Map ?!
A map interface that can be used in clojure code.

Besides some added convenience, I assume that a motivation is to expose the capability of atomically updating some key values?

(note to self)
We can test the collection implementation by using guava testlib

It might be helpful to leverage a high performance caching solution to implement this:
