This looks like it's doing too much work to simply generate a random
integer. Are you sure you want to build a lazy list of 999,000 integers
and randomly select into it for every invocation? The garbage collector
will be working overtime.
(defn update-individual [json-string]
(assoc-in json-string ["someInfo" "moreInfo"]
(rand-nth (range 1000 1000000))))
This should get you a random number in the range without as much effort.
(+ 1000 (rand-int 999000))
