- * 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. - *

- *

- * It also provides the ability to control the lazy loading queries (batch size, - * selected properties and fetches) to avoid N+1 queries etc. - *

- * 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. - *

- *

- * You can use query() and lazy together on a single join. The query is executed - * immediately and the lazy defines the batch size to use for further lazy - * loading (if lazy loading is invoked). - *

- * // .. then if lazy loading of customers is invoked
- * // .. use a batch size of 5 to load the customers

- *   .where().eq("status",Order.Status.NEW)
- *   .findList();
