Neo4J APOC Periodic Iterate – ReferenceFromSlot(2) to be a map, but it was :`NO_VALUE`”: 4
I have nodes of label TypeA which have a string property, propA. propA is a string JSON and can be converted to a map using apoc.convert.fromJsonMap().
Renaming Labels of relationships in Neo4j using parallel processing
I have a lot of relationships in my Neo4j Database for which I have to rename labels. As the number is quite high (close to 13 million), I am processing parallelly for faster execution. I believe my Cypher Query is correct, but a weird error is getting thrown by the system:
Real relations from graph shows up when i try to create a sub-graph with virtual relationships
I have two large graphs in my database. Here is a query that works fine when I use it on the first graph:
Cypher query to find nodes where all relationships have a given property? ( deleted_at )
I choose to soft delete relationships on my graph, but I expect my nodes to have a single “active” relationship of a particular type. I ran into a scenario where some of my nodes ended up having all their relationships pick up a deleted_at property, and I ran into trouble isolating them for investigation.
Neo4J Graph Cypher Query – Formula Relationship Traversal
This graph model represents BusinessRule nodes (formulas) and ChartField nodes (values). A BusinessRule node will have “USES” relationships with ChartField nodes that are parameters for the BusinessRule formula. The BusinessRule will have 1 “OUTPUTS” relationship to a ChartField node that is the target of the BusinessRule calculation.
