  description: >-
    Spring Data REST exposes Spring Data repositories as hypermedia-driven
    RESTful resources following the HATEOAS constraint. It provides automatic
    endpoint generation for CRUD operations, pagination, sorting, projections,
    and custom query endpoints derived from repository methods.
