I am receiving the stringified datalog query as one of the values inside a JSON request. Before executing the query, I need to modify it in my Clojure code to add some more conditions. I was unsure about the approach that I should take - should I proceed with string concatenations or should I convert the query into Clojure data structure and then proceed with modifying that data structure. I tried to search for some examples but wasn’t able to find any. Could you please suggest me what would be the better approach.
