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 referred this site to convert my existing mongodb data to neo4j with relationships mappings. I used the following query to fetch data from mongo to neo4j db. CALL apoc.mongodb.get('connectionString','dbName','TableName',{}) yield value CALL apoc.gr...
When I run the following query, it extracts the path between nodes. //ShortestPath planning match (g:Id1 {start_marker:1}), (c:Id2 {break_point:1}), p = shortestPath((g)-[*]->(c)) return p Extracted path from the graph: Then I extract...
Hello everyone, I am actually working on a database (Community version 4.4.4) and facing an issue. I am wondering how neo4j deals with a list of properties (either on nodes or on links). I am trying to find longest coherent path and what I want to do...
Is it possible to reuse the same execution plan for similar pattern? In my example I have a structure the looks like this: Essentially, for each time I always start from node (A) and traverse and retrieve the node (D) in different combinations based...
Hi I imported 465 triples into my graph database using Neosemantics app. It took 210ms to complete the job. I then imported 945 triples into the same graph database and it took 78ms. My understanding was as number of triples increase the time taken t...
Hello Everyone, I am new to Cypher and having issues while querying for multiple relationships. I have two relationships :abc and :xyz. I want to get all the nodes that are 2 hops away which have either :abc OR :xyz relationships. Also, :abc is dire...
I have a graph containing many nodes. Each node in the graph has the same properties with different values. I loaded the graph efficiently using: CALL apoc.periodic.iterate('LOAD CSV FROM $url AS data FIELDTERMINATOR "," return data', 'CREATE (:G {x:...
Hi I hit a problem that we think one of our user table data/node which is broken, we can not query it or all of user data(it will stuck and the CPU up to 100%), and can not delete it even we know its uuid. MATCH (n:Neo4jEmployee {uuid:'95536edb-013d-...
What is the impact, if any, of creating indices on a labeled node that are unused in many instances of that node? More specifically, what is the impact on write performance, read performance, and space? I'm using neo4j-enterprise v4.4.4. I have a lab...
Hi, I have exported my Neo4j database to a CSV with the following: < CALL apoc.export.csv.all("movies.csv", {}) /> And I want to import this CSV file to another Neo4j database. How do I do it? I'm not interested in importing a Cypher file with apoc....
Hello, I have 3 nodes cluster running in K8 (GKE), using the official helm-charts. All works very well, but from time to time I run into issues after restarting one of the nodes. There are 10 graphs in the cluster, all of them are relatively small, j...
My neo4j version is 3.5.30, there are only 12 color for nodes in different labels. But I have more than 12 nodes in different labels, I want to show each nodes in different color. Are there any ideas to expend the number of color in neo4j browser?
Hi, I'd like to know how can I use cypher like SQL function "rank over partition by". For example, I want to get 1st rank data by subject, class. I'd appreciate advice. Ex) Class Subject Score 1 Math 99 (Y) 1 Math ...
Hi, Can I load a standalone Neo4j 3.x instance using a dump file generated by the Causal Cluster online backup policy ? If yes, how long does it take (aprox)? (the xxx.dump.tar.gz has a size of 1.7 GB) Is it a bad practice? The standalone neo4j is in...
query1: match p=shortestpath((a:A)-[e:E*1..3]->(b:B)) return p,size(e) AS steps query2: match p=allshortestpaths((a:A)-[e:E*1..3]->(b:B)) return p,size(e) AS steps I did some tests and they all got the same result, my expectation is that if there ar...
