Bulbflow: difference between neo4jserver Graph and neo4jserver Neo4jclient

阅读更多关于 Bulbflow: difference between neo4jserver Graph and neo4jserver Neo4jclient

I am now trying to learn how to connect to Neo4j server and run Cypher queries on it using Bulbflow from Python. And the thing I do not understand is the difference between two possibilities to connect to the neo4j server: 1) Graph from bulbs.neo4jserver import Graph g = Graph() 2) Neo4jClient from bulbs.neo4jserver import Neo4jClient client = Neo4jClient() Could anyone please explain the conceptual difference here? And which way is it better to choose if I then want to execute (quite a lot of) Cypher queries against the server and ultimately in parallel? PS: I do not have enough reputation to

ORM with Graph-Databases like Neo4j in Python

问题 i wonder wether there is a solution (or a need for) an ORM with Graph-Database (f.e. Neo4j). I'm tracking relationships (A is related to B which is related to A via C etc., thus constructing a large graph) of entities (including additional attributes for those entities) and need to store them in a DB, and i think a graph database would fit this task perfectly. Now, with sql-like DBs, i use sqlalchemyś ORM to store my objects, especially because of the fact that i can retrieve objects from the

Choosing an appropriate way to use Neo4j in Python

阅读更多关于 Choosing an appropriate way to use Neo4j in Python

I am currently using embedded python binding for neo4j. I do not have any issues currently since my graph is very small (sparse and upto 100 nodes). The algorithm I am developing involves quite a lot of traversals on the graph, more specifically DFS on the graph in general as well as on different subgraphs. In the future I intend to run the algorithm on large graphs (supposedly sparse and with millions of nodes). Having read different threads related to the performance of python/neo4j bindings here , here , I wonder whether I should already switch to some REST API client for Python (like

Is there any object-mapping

Use neo4j with R

阅读更多关于 Use neo4j with R

问题 Is there a R library that supports neo4j? I would like to construct a R graph (e.g. igraph) from neo4j or - vice versa - store a R graph in neo4j. More precisely, I am looking for something similar to bulbflow for Python. Update There is a new neo4j driver for R that looks promising: http://nicolewhite.github.io/RNeo4j/. I changed the correct answer. 回答1: Consider the RNeo4j driver. The function shown above is incomplete: it cannot return single column data and there is no NULL handling.
