@vijayakkineni A reason you are not getting any answers might be that a lot of people are using clj.spec now instead: http://clojure.org/guides/spec
@vikeri thank you, yep i have ben using spec. I started using CQRS kekkonen and it is not supportin clojur.spec yet so thats the reason for asking. Anyways i think i figured the answer to the above question. We could use s/btoh and have not-empty? predicate which checks the map to be empty or not.
Alright great!
