Introducing Neo4j Workspace We’re inviting you to check out Neo4j Workspace. Workspace combines our most powerful graph tools (Data Importer, Bloom, and Browser) all in one place to help you get up and running with graph databases faster. For experie...
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...
Hi, I received a task to do and I have no idea how to make it. I have a few GB of data in CSV format which I have to import to Neo4j Aura. Each CSV is an undirected graph (tree) with array notation of nodes positions - Joe, [] Pat,[0] Corbin,[1] Mike...
Hi all, The node similarity algo (from GDS) considers all the outgoing relationships from a node and computes similarities on the basis of the same. Can we somehow consider both incoming and outgoing relationships while using the node similarity?
MATCH (n) WITH n.Name as name WHERE name ENDS WITH ' ' SET name = rTrim(name) return name I want to find nodes whose Name has trailing space and remove that space, but the command gives this error: Type mismatch: expected Map, Node or Relationship ...
Hello there The title says everything, On Google Cloud, Compute Engine or Kubernetes engine to host Neo4j? If Kubernetes is so great and better than Compute Engine why Neo4j is still providing compute engine images? What's the down sides of Kubernete...
I am having difficulty making sense of an issue with a graph. here is the issue: traversing a path from A to Z yields a count of zero but traversing the path from A to B gives a result of 1 and from B to Z gives the result of one. How is that even p...
Hello there Roughly, what type of machine you recommend on Goolgle Compute Engine for a Neo4j database needs? I mean n1,e2,etc. ? HightMemory or HightCPU, SSD or HHD disk? I already know how to set the ram and space size according to our needs. (16 G...
Hi, I have two versions of Java at my server 1.8 and 11 (other apps require 1.8) For neo4j.bat I simply set java_home inserting line: SET "JAVA_HOME=C:\Program Files\Java\jdk-11.0.4" How to manage it for neo4j install-service? Where I should set java...
Hi, I'm not too sure if this is the best category to post this question. I have a JSON-LD-Star file with "@annotation" properties. Can Neo4J+APOC import this type of file? So far, I haven't found a way. n10s.rdf.import.fetch(..., "JSON-LD") appears t...
I have an instance with 1GB of RAM, and my queries are dying with something like The allocation of an extra 12.0 MiB would use more than the limit 100.0 MiB. Currently using 92.0 MiB. dbms.memory.transaction.global_max_size threshold reached This pos...
I database neo4j 20 million Nodes and 20 million Relationships. I want my algorithm page Rank to be used. It has been running for two days now, I still do not see any output, your suggested solution to solve this problem. The code is written as follo...
Hello all, I'm trying to compute predictions for certain properties in group of nodes, it resembles the solution provided by Lauren Shin in https://towardsdatascience.com/graphs-and-ml-multiple-linear-regression-c6920a1f2e70 except that the model is ...
For a data like this: create (a:User{id:'1'}),(b:User{id:'2'}),(c:User{id:'3'}) I'd like to get all User nodes, and its total count with one query. I first tried this: match (u:User) with u, count(u) as total return u.id, total But this gives the f...
Hi All, I am converting a (let's say relational) system into Neo. In the current system, we generate a unique ID for each new row. The ID is only 5 digits, alpha numeric e.g. '01BJF' and is generated sequentially (the next id would be '01BJG') and ...
Hi Is neo4j or GRANDstack suitable for knowledge management / mindmaping + project management / tasks / todos / process/checklist app? The Problem Context is I have a whole lot knowledge, projects, mindmaps, notes, files, etc spread out across everno...
Please have a look at a model below to understand the problem encountered. A question regards adding new tail nodes to the model here 'X' node. New nodes are to be fetched via a data file containing a dozen of rows with each line representing one nod...
