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...
I have a simple doubt. Can't we write stored procedure in cypher itself and use it like other SQL databases? Is using Java is the only option we have??
I am just trying to learn Neo4j with cyper here is the use case I want to find all the nodes with and without relationships match p=(a)-[]->(b)with p limit 25 unwind nodes(p) as n unwind relationships(p) as rwith collect( distinct {id: ID(n), label...
I have a query optimisation problem... What I want is effectively the same as the problem in computer science of managing multiple concurrent workers when you only care about the first successful result that you get back (fastest), and then you want ...
A node can have 1-2 relationships with a node. Either a node leads another node i.e (A)-[:Leads{subtype:"1"]->(B) or a node mentors another node similar format as Leads above or a node leads and mentors a node so A=B (both lead and mentor relationshi...
Hi everyone, I am working on a huge graph consisting of 230M nodes and 600M edges. I trained embeddings with using built-in FastRP algorithm. The final objective is finding similar nodes with reference pivot embedding. When evaluating embeddings, cos...
Hi all,I have the following short query, which reads a 40.000 lines input files, but suddenly stops after the first line. LOAD CSV WITH HEADERS FROM 'file:///Customers/data.csv" as row FIELDTERMINATOR ';' WITH row, trim(row.`nome del produttor...
Good morning experts, i can't see the relationship between my data, there is no error and it's mentioned no changes no records this is my code CREATE CONSTRAINT ON (c:LIBELLEPDT) ASSERT c.id is UNIQUE;CREATE CONSTRAINT ON (c:AssetClass) ASSERT c.nam...
Hi,I'm trying to add a calculated property to each of a bunch of nodes based on the 'SentText' property of that node (a BERT sentence embedding vector calculated in Python in this case).I've found an example of apoc.periodic.iterate below (https://to...
Dear All, Wishing you all a Very Happy New Year! Quick one..Recently Ive completed a Data Model for Industrial IoT use case where in ive modeled the Asset Hierarchy as well sensor data . Time series data for every min from around 100 sensors from the...
Hi Neo Friends!The query below is a modified version of a query I made that works when I am searching in the CONTAINS clause for only a single product type, but I've tried multiple ways of searching for more than one, such as making a list with comma...
Hi Experts!I downloaded the tar version of the neo4j 4.4.7 and installed it to Linux and Mac, moved the apoc .jar in labs to plugins. (I think this is pretty straight forward as an initial setup..)When I looked at neo4j.log, I found the following ent...
Hi everyone, I have the following situation. I am sinking data from Kafka to Neo4j using the Kafka connector Neo4j connector. I have 44 topics from which I should read from and some of the topics are intersecting with each other, which means that dur...
Hi, My DB has around 2 million nodes(10 different types of nodes) and 3 million relationships in total. Problem: I want to run a query on the DB and select a set of nodes (similar type) based on the presence of a keyword(or phrase) in one of their fi...
Dear Community, we are Connor and Daniel, Software Engineers at Anaconda, and we are currently looking at neo4j to represent our package meta data to answer questions like: What packages are available for python X on platform Y but not on platform Z?...
I need a query that finds nodes without a specific relationship. The following query works: MATCH (e:Entity) WHERE NOT (e)-[:CHILD_OF]->() RETURN e But neo4j browser gives me the following warning:This feature is deprecated and will be removed in f...
