+### EfQueryComplexity
+
+Detects overly complex queries and either logs them or throws. Checks include unbounded result sets, maximum `Take`, expression node count and depth, navigation and include depth, collections in a single query, and `IN` list size. Useful for bounding queries shaped by untrusted clients, such as through GraphQL or OData. For EF Core: 10.
