The Neo4j Graph Platform includes the core database and all the technologies surrounding the database, making it useful and accessible for a lot of different users. When asking a question, please select a descriptive label that best matches your quer...
From my understanding, the original GraphSAGE algorithm only works for homogenous graphs. For heterogenous graphs to work, a lot of changes have to be made to the message passing algorithms for different nodes. Does Neo4j's GraphSage work for Hetero...
neo4j community server 4.3.3 on Ubuntu 20.04 Dear all, there is a strange behavior in the OPTIONAL MATCH. Maybe, I misunderstood, but would be nice if someone could explain me. I have this simple query: MATCH (x:X {uuid: 'ccc9c72a-3a1d-4683-8cf9-c98...
How do I do multiple aggregations in Neo4j without repeating my MATCH query? Let's say I have a database consisting of customers, the restaurants they go to, and the record of the bills for each customer/restaurant for a particular year. Note that a ...
Do the terms of use for "neo4j Desktop" apply to the ONGDB server which I downloaded under AGPLv3 license? I read the Desktop terms carefully and they refer everywhere to "neo4j Desktop software". Has anybody encountered this issue? I am feeling real...
Hey, I have neo4j db. I am looking for way to open graph from file(json, xml or something like that) but without saving the nodes and overwriting what I have now in the db, just visualize it. Any suggestions? Thanks in advance.
Hi, Newbie here. For a story I'm trying to import 330.000 json documents on academic papers, with relationships between papers, authors, institutions, funding and patents. I'm using apoc load json for this, but it's terribly slow, it's starts out pr...
when trying to restore in new database from json file, the operation stops with below error Failed to invoke procedure apoc.import.json: Caused by: com.fasterxml.jackson.core.io.JsonEOFException: Unexpected end-of-input: was expecting closing quote f...
I am experimenting with Nestjs, graphql, and neo4j-graphql with augmented schema. I am interested if anyone doing any work in this area. The main challenge I am having relates to neo4j-graphql-js and the code-first concept. So from my understanding n...
I want to import a large json dataset using apoc library, and create nodes - relationships. My script was working slowly (~750000 records). Neo4j Community suggested to batch the records for more efficiency. Firstly, what method should i use ? Period...
I just installed neo4j desktop and tried to run movie database but it gives error. Version is 4.1.0 Windows 10. I could not understand what is wrong from logs. Database failed to start: DB [database-5db1a868-35bf-44e0-a100-13442dfbbbe6] 'v4.1.0' exit...
Hello: All the documentation states that Jaccard is an alpha algorithm and should be in: gds.alpha.similarity.jaccard but it's not there! This is so in both a desktop version and a community edition. I wonder if it has now been restricted to just the...
What is the best practise around APOC triggers: Is it disadvised to put business logic in them? What kinds of logic should go in them, and how much? Will logic in there tend to grow to a maintainability burden over time? I imagine one might have APOC...
Hi all, I am looking for help on importing large arrays into neo4j. I currently create data by solving differential equations, varying parameters and generating at least large 2+ dimensional arrays. Say a spatiotemporal array over R^3 (x,y,z) and tim...
Hi Team, Need your thoughts on getting below error line in neo4j debug logs of 3.5.3 Neo4j version 2021-10-16 18:55:44.215+0530 ERROR [o.n.k.i.t.l.c.CheckPointerImpl] Checkpoint failed Unexpected log file header. Expected header version: 44866, actua...
Hi. I'm learning neo4j and I have to make a simple query, but I'm not able to make it. Suppose to have the graph below. I want to return all the nodes connected to the node A and the maximum of the values on the edges between two consecutive nodes(wh...
