Neo4j Graph Output
The algorithm used to update your graph takes null values for fields mapped to primary properties of nodes into account. These will not merge on these nodes, nor will it create or update relationships to these nodes.
- Updates across unknown nodes are not supported
Try a modeler like Cypher Workbench or and import the result into a Graph Model.
Make sure that every defined node has a primary key field
Limit yourself to one primary key field per node
- Make sure that every node primary key has an index. Use the provided button in the graph model editor to generate the Neo4j Index and Constraint actions which will handle this for you.
