Spring Data Neo4j 4 and dynamic properties

At my Neo4j/SDN 4 project I have a following entity:

@NodeEntity
public class Value extends BaseEntity {

    @Index(unique = false)
    private Object value;

    private String description;

...

}

During the application run-time I want to be able to add a new dynamic properties to Value node, like for example value_en_US, value_fr_FR.

Right now I don't know what exact properties will be added to a particular Value node during application run-time so I can't define these properties at the code as a separate fields in Value.

Is there at SDN 4 any mechanisms to define these properties during the application run-time? I need something similar to DynamicProperties from SDN 3.

Solution

  • There is no such functionality in SDN 4, but it will be added in SDN 5 through a @Properties annotation on Map.

    It will be available for testing in snapshot version very soon. Check out this commit for more details
