Its mechanics are straightforward. Its solutions are well-documented. Its persistence in production systems reflects the gap between understanding a problem and implementing a solution that holds under all the query patterns a flexible API allows.</p> <p>A GraphQL query that requests a list of posts and the author of each post produces, in a naive resolver implementation, one database query to fetch the posts and one database query per post to fetch each author. A query requesting 100 posts with their authors produces 101 database queries. A query requesting 1,000 posts produces 1,001. The number of database queries grows linearly with the number of items in the list — hence N+1, where N is the list length and 1 is the initial list query.</p>
