Clojurians Log v2

I'm trying to use Java interop

but I'm kinda newbie hahha

(defn create
  "Takes a map of keyword-value pairs and puts a new Entity in the Datastore.
  The map must include a :kind String.
  Returns the saved Entity converted with entity-to-map (which will include the assigned :key)."
  ([item] (create item nil))
  ([item #^Key parent-key]
   (def key (.allocateId dataStore (.newKey keyFac)))
   (let [kind (item :kind)
         properties (dissoc item :kind)
         entity (Entity/newBuilder key)]
     (doseq [[prop-name value] properties] (.set entity (name prop-name) value))
     (.getId (.getKey (.add dataStore (.build entity)))))))

I'm having problem with this

I'm trying to take a map from a jdbc query into a ms-sql db and inserting the data into datastore
