问题 I have a python flask web app, which is querying a Janus graph DB using gremlin_python . One basic question is the correct way to initialize the graph traversal object. Can I initialize my traversal g = traversal().withRemote(DriverRemoteConnection(...) and persist the traversal variable g across requests? (All requests are against the same graph. I tried this and started getting tornado.iostream.StreamClosedError intermittently. Second option is the create a traversal per request. I do not

问题 I want to ask you about the best way to use graph database (Neo4j) in Python. What you think, should I use "neo4j/python-embedded" (neo4j/python-embedded with JPype) or maybe "bulbflow" (bulbflow, with Rexster, Gremlin and REST api)? Is REST api secure and provides high availability (e.g. 500 000+ users)? Thank you. 回答1: I think Bulbs against Neo4j Server might be the best combination. Also, you can set up Neo4j in High Availability mode so multiple instances are forming a cluster, http:/

问题 I am using the orientdb and gremlin server in python, Gremlin server is started successfully, but when I am trying to add one vertex to the orientdb through gremlin code it's giving me an error. query = """graph.addVertex(label, "Test", "title", "abc", "title", "abc")""" following is the Traceback /usr/bin/python3.6 /home/admin-12/Documents/bitbucket/ecodrone/ecodrone/test/test1.py Traceback (most recent call last): File "/home/admin-12/Documents/bitbucket/ecodrone/ecodrone/test/test1.py",

问题 Abstract I'm trying to set up a Titan/Cassandra/Gremlin-Server stack in Docker (v1.13.0). The problem I'm facing is that applications trying to connect to Gremlin-Server on the default port 8182 are reporting errors (details below). First, here is some relevant version information: Cassandra v2.2.8 Titan v1.0.0 (Hadoop 1) Gremlin 3.2.3 Setup Setup takes place in a Dockerfile in order to be reproducible. It assumes that a Cassandra container already exists, running a cassandra.yaml in which

How do I connect to a remote Neo4j database using gremlin python?

问题 From what I've read Neo4j implements apache tinkerpop which leads me to think I can use gremlin python and rather than connect to a gremlin server I can point the python code at a neo4j server and treat it like a gremlin server. However I can't find any information online which shows how to do this so I'm thinking maybe I've misunderstood something. a) Can I use gremlin python directly with a neo4j db instance? b) If yes to (a) then how? Thanks Alex 回答1: You can not connect gremlin-python to

Thanks Alex You can not connect gremlin-python to Neo4j Server. gremlin-python contains drivers that connect to Gremlin Server so you must have that installed
