Good day. I've gone through the basic Neo4j and Cypher lessons. However, I have yet to start my first project -- until now. I'm a little rusty on what I studied in the spring. I have a list of employees who travel and work around the world. The em...
I am curious if there are tools to migrate/populate a relational database from Neo4j? I have seen numerous articles on migrating from a RDBMS to Neo4j, but not the other way around. Looking to use the relational database for reporting. Thanks.
So when i remove the grey node, the green, pink and darkgreen nodes will be deleted as well. I tried: session.delete(thisnode.class, id, 5) And a cypher solution is fine too, this didnt work either: MATCH (n:thisnode)--(e) DETACH DELETE n,e; What wo...

I want to return all nodes/relationships until I find the first node that has a certain relationship in an arbitrary number of iterations. Example Given: X(1)-[foo]->X(2)-[foo]->X(3)-[bar]->X(4)-[foo]->X(5) I want this returned: X(1)-[foo]->X(2)-[fo...
I apologize if this is a common question, but I haven't seen any clear and definitive answer so I figured I'd ask.. Part of our structure requires that we track changes to a given entity - lets say, a "person". Now, this person may have a name, ID, o...
I try to import Musicbrainz database from the example datasets https://neo4j.com/developer/example-data/. I downloaded the 4.5GB big file archive and dezipped the whole database to a new graph.db folder. When I now try to start the database after suc...
Hi Neo4j Community, I hope its okay that i opened a new topic, but im stuck for 2 days. So i got a Database with Persons as Nodes and each "Meeting" of each other i displayed as Relationsship with the property datetime. Here's one extract from the da...

I am using Neo4.0 and I want to install the exactly same graph as multiple instances of neo4j on the same machine and run them at the same time. Those multiple instances can concurrently handle users' queries from client, and the hope is to maximize ...
Hello, On my server, I was using a working instance of Neo4j 3.5.0. On my computer, I was using version 4.2.0. I updated my version on my server to find the same configuration. sudo add-apt-repository "deb https://debian.neo4j.com stable 4.2" sudo ap...
The documentation only says: # Number of Neo4j worker threads. # dbms.threads.worker_count= In another post I saw that this parameter only works for rest api request. Is that true? If not, I am using Bolt driver, what's the default work count and sh...
Hi there, I am looking to list all of the triangles in some large graphs from stanford. (one example is the web-Google graph) It seems that gds.alpha.triangles is exactly what I want, but when I run the algorithm, only about one tenth of the triangle...
How Neo4j search data if i search nodes with the label. If i use profile/explain the operator that shows was NodeByLabelScan. My specific question here is, does Neo4j maintain additional storage(or any special kind of indexed data) so that, while pro...
