All applications using Neo4j depend on drivers to execute statements to update or query data. Neo4j drivers are mostly built on the binary Bolt protocol. Official drivers exist for Java, JavaScript, .Net, Python, and Go and more. Other languages (R, ...
I have this relationship Node1 ---- HAS ----> Node2 I want to make sure that the "name" property in Node2 is unique within it's parent node - Node1. Is it possible to enforce that using Neo4J-OGM? Or do I have to make a separate get call before calli...
Hello, org.neo4j.ogm.session.delegates.SaveDelegate#save(T, int) is taking a depth parameter but not SaveEventDelegate#preSave. The visit of the nodes can be pretty extensive. Is it on purpose?

Should I use Neo4j driver or py2neo to read and write neo4j databases in Python?What's the difference?
For those interested on build real-time applications on top of Neo4j, I've just written a blog post on how to use Neo4j Streams and Kafka to pass updates from the graph into a front end application - in this case written in Vue.js. adamcowl...
Hi! I use github.com/neo4j/neo4j-go-driver/neo4j. And I work with stack go-graphQl-neo4j. If I send query to NEO4J from queryResolver and from mutationResolver-it's ok. But when I use custom Resolver and I send simple query to neo4j (even "Return 1")...
