Hello all, I am trying to understand better EclipseLink NoSQL, but I am having trouble understand it's limitations, what it currently supports and I simply can't find anything about the future plans the team has.

So, in short, I have quite a big list of questions that i would like to know, if you people don't mind:

Does EclipseLink support:

  1. Object Oriented queries
  2. CRUD of entities
  3. Polymorphic entities
  4. Embeddable objects (components)
  5. Basic types
  6. Unidirectional and Bidirectional relationships (if yes, which ones?)
  7. Collections (Set, List, Map, etc)
  8. Full JPA support (I assume it does, but just in case I am wrong)
  9. Denormalization
  10. Complex joins and aggregations


Apart from these questions, are there any other limitations or jewels of the crown that I should know of?
Also, what is the team currently working in? What are the future plans?

I would be super happy if someone here could provide me with links or documentation for the questions I provided above, since I couldn't find anything :S

Thanks in advance, Pedro.

In an effort to complete the content of this discussion, I am now posting what I have found.

Currently (use discussion date as reference) EclipseLink Supports:


  • Complex hierarchical (including XML)
  • Indexed hierarchical data
  • Mapped hierarchical data (such as JSON)
  • CRUD operations
  • Embedded objects and collections
  • Inheritance
  • Relationships
  • Subset of JP-QL and Criteria API, dependant on NoSQL database's query support


Questions without answer:
- Current limitations
- Future plans
