I have a huge array of records, each with a unique value in json.rest. Each entry with its own zson.rest key value is first displayed in one record from the first service, then in the next record from the second service. My task is to compare the number of records that got from the first service to the second, tracking each of them by this unique value. How can this be done with only view access?
