Fair enough- since the sample application supports deleting entities, the problem may arise, even with short lived sessions. We'll update SDN4-University for this. Regards Luanne On Fri, Mar 25, 2016 at 11:33 PM, Tim Colson wrote: > SDN only uses the internal node id's

Re: [Neo4j] How do Entity IDs in sdn4-university work?

Hi Tim, SDN only uses the internal node id's to attach entities to the graph. Since these entities should be managed by SDN within the context of a Session, which is relatively short-lived, it isn't a problem. If you delete entities externally i.e. not via SDN, then please make sure that your

Hi Tim, SDN uses the internal Neo4j node or relationship ID to track domain entities. This is the same as in the Neo4j browser. The @GraphId annotation is used to indicate which java.lang.Long

Hi Ivan, When you create relationships, are the nodes on either end already persisted? Or are you creating both new nodes and relationships to those in one go via the save with depth -1? How many relationships approximately are created via a single save? -Luanne On Wed, Nov 18, 2015 at 6:16 AM,
