EclipseLink's support for MongoDB includes:

  • Mapping of @Entity for root and @Embeddable for nested data
  • Mappings of type @Basic, @Embedded, @ElementCollection, @ManyToOne, @OneToOne, @OneToMany, @ManyToMany
  • Inheritance
  • Optimistic locking
  • Generated values, OIDs
  • CRUD operations (persist, merge, find, remove)
  • JPQL and Criteria API queries,
    • sub-selects, group by, and certain functions are not supported
  • JPA Query options firstResult, maxResults, fetchSize
  • MongoDB query options read-preference, write-concern, options
  • Native queries (through MongoDB's command language)
