Hello. Is any way to allow Neo4j to use Linux swap file for pagefile? I made it with 'swapon', increased 'dbms.memory.pagecache.size', but got "ERROR Invalid memory configuration - exceeds physical memory. Check the configured values for dbms.memory....
Hello I developed a Python script to model a SDN (Software Defined Network) topology as a graph in Neo4j. In addition, the Python script can retrieve traffic statistics from the SDN controller to be stored as node &/or relationship properties. I want...
I follow this Link to use a graph generator to create a graph scaling to +10000 nodes and to execute the shortest path algorithm between two nodes. How can I set the relationship property for all the nodes to be in a specific range? This Link provide...
Hi Everyone! In the previous version of the database there was the traversal framework in the Java API. It was really helpful in making some complex queries. But since the version 4 the method of getting TraversalDescription from the database object ...
Hi, we were running neo4j 4.0.2-enterprise in a development Amazon EKS cluster for some time. I tore the cluster down and tried to rebuild it, this time bumping the container up to 4.1.1-enterprise. This is what happens in the neo4j logs: Changed pas...
Hi, I'm developing a project that consists in a real time movie recomendder system and already did the project in Python, but need to implement it in Neo4j, in order to compare their performance. However, I don't have a lot of experience with Neo4j a...
What is considered best practice with storing Documents (hundreds/thousands of words) in Neo4j. If for instance, I am creating a knowledge graph, that includes articles/blog posts, I can store the properties and categories as relationships. But for t...
I am trying to get the top 10 values of a property P1 in node N1 for each property P2 in the same node N1. So far I have tried the following: match (n:N1) where n.P2 is not null with n.P2 as test, count(*) as times with collect ({P2:test,times:time...
I have a lot of triplets (node, relation, node or circle, relation, circle) with different attributes for each user node (it can contain user_id, location, role for some nodes and others can be without location but with their marital status, use_car ...

Hello, I've been using the Dijkstra Source-Target algorithm of the GDSL plugin to get the shortest path between two nodes. That works exactly as it should be, however I always have to rerun the cypher query : CALL gds.graph.create( 'graphname, 'node'...
