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...
We are looking at using a Graph DB (e.g. Neo4j) for modeling and analysis of quality issues in a manufacturing production line. I.e. there are set of connected nodes that represent materials and assemblies as well as the operations that are done to a...
Where can I learn about the minimum system hardware requirements to use Desktop Browser to visualize graphs with some million of nodes? In particular, the minimum requirements for the graphics card?
Hi Everyone In the last few months, I've created a central database pulling data from several other systems. As a next step it should become a hub for all kinds of dataexchange. I am currently trying to update a MySQL database with the contents of my...
Hello, Does anyone know something else to visualize temporal graphs, instead of https://gephi.org/ (https://vimeo.com/9726202) ? Asking as Gephi has not been updated since Sep 2017. Regards, Gabriel
Hello, I am new to neo4j and I want to embedd neo4j in an OSGI server. I have created a neo4j-api bundle which embedd all neo4j related libraries and have created a neo4j-store which use the neo4j-api bundle and create an embedded graph database. I h...
Copied from initial slack discussion to keep track of the outcome: Currently I have a database with multiple sub graphs (disconnected from each other). This seems like a perfect fit to create a database for each sub graph. I understand I can supply t...
While reading a elastic index into neo4j, there are fields with null values, I use below code to read and get the error MERGE (applicationgisno:ApplicationGISNo {appgis: applicant.GIS_No}) MERGE (doc)-[:GIS_No]->(applicationgisno) #if the value is n...
Hello, I have a query and when I use the where clause, I get different results from a table and from a graph. I enclose my query and two images to show it: MERGE (ipo: ipOrigen {ip: line[2]}) MERGE (ipd: ipDestino {ip: line[4]}) with ipo,ipd,line CR...
Is it possible to get total and paging data in one query? Say I have 100 total rows and my output looks like { "total": 100, "list": [1, 3, 5, 7, 10] } I tried to achieve this with a query like MATCH (:User {uid: $uid})-[:R1]->(:Chat)<-[:R2]-(:P...
Hi, I am trying to run pageRank algorithm for a sample graph dataset Twitter-2010 dataset. I have a 64GB RAM linux server, where I have set up neo4j using the Unix tar.gz available (community edition) Importing the data was done in good time. But wh...
Hi, In Elasticsearch Integration Using CALL apoc.es.query i connect to my elastic index, then I unwind the hits as hit, and access each property as MERGE (applicationid:ApplicationID {appid: hit._source.Application_ID}) MERGE (doc)-[:HAS_ID]->(applic...
Hi, everyone, I have 10,000 nodes which interact with each other (one node interacts with other 9,999 nodes). I generated cypher queries for each node and relationship and then call call_neo4j function in R package Neo4r. Then, I use merge operation ...
HI! When I try to use apoc.coll.intersection, it doesn`t work. I see the error: there isn't such procedure. But apoc.coll.set works correctly. version - 3.5.0.4 Added to conf file: dbms.security.procedures.unrestricted=apoc* I see this issue on Windo...
Can we run multiple graph algorithms at once say betweenness, pagerank, eigenvector, strongly connected, then export the results as csv for each nodes?
Will it be possible to combine results from multiple databases in a single query? Hive and Spark for example support something like this: SELECT sales.id, sales.amount, hr.id, hr.person FROM sales_db.sales AS sales INNER JOIN hr_db.employees as hr O...
