- * Defines the configuration options for a "query fetch" or a

- * <p>
- * The primary goal is to provide efficient ways of loading complex object
- * graphs avoiding SQL Cartesian product and issues around populating object
- * graphs that have multiple *ToMany relationships.
- * </p>
- * <p>
- * It also provides the ability to control the lazy loading queries (batch size,
- * selected properties and fetches) to avoid N+1 queries etc.
- * <p>
- * There can also be cases loading across a single OneToMany where 2 SQL queries
- * using Ebean FetchConfig.query() can be more efficient than one SQL query.
- * When the "One" side is wide (lots of columns) and the cardinality difference
- * is high (a lot of "Many" beans per "One" bean) then this can be more
- * efficient loaded as 2 SQL queries.
- * </p>
+ * Defines how a relationship is fetched via either normal SQL join,
+ * a eager secondary query, via lazy loading or via eagerly hitting L2 cache.

  * List<Order> list = DB.find(Order.class).fetch("details").findList();
