**[How To Implement Pagination Via `ROW_NUMBER()` Window Function](< B41A span class="pl-corl">https://github.com/AnghelLeonard/Hibernate-SpringBoot/tree/master/HibernateSpringBootPaginationRowNumber)**
2+
3+
**Description:** This application is an example of using `ROW_NUMBER()` (and `COUNT(*) OVER()` for counting all elements) window function to implement pagination.
4+
5+
**Key points:**
6+
- use a native query relying on `ROW_NUMBER()`
7+
- we don't return a page as `Page` or `Slice`, we return it as `List`, therefore `Pageable` is not used
