N+1 Query - CI/CD Glossary Definition

An N+1 query problem runs one query for a list plus one per item, causing N+1 database round trips.

An N+1 query problem is a performance issue where code runs one query to fetch a list, then one additional query per item, resulting in N+1 total round trips.

N+1 patterns often pass tests but slow production; some teams add query-count assertions in CI to catch them before deploy.
