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

You can not connect gremlin-python to Neo4j Server. gremlin-python contains drivers that connect to Gremlin Server so you must have that installed for gremlin-python to work. Given that you need Gremlin Server you must choose one of the following options all of which are just Gremlin Server configurations:
- Configure Neo4j in embedded mode within Gremlin Server. An example of this is here where that file points to a Neo4j configuration file. Note that these files are packaged in the Gremlin Server distribution as samples so you can run them directly quite easily.
- Modify the aforementioned Neo4j configuration file to run Neo4j in HA mode effectively turning Gremlin Server into a node in the Neo4j cluster.
- Configure a neo4j-gremlin-bolt instance which will use the Neo4j Bolt protocol to connect to the running Neo4j Server. While I"m not completely familiar with this implementation, I can see that you would change the
gremlin.graphtocom.steelbridgelabs.oss.neo4j.structure.Neo4JGraphand that you would discern Bolt configuration options from this class (which instantiates that graph instance).
Once you've chosen one of those configuration options you can then use gremlin-python to work with Neo4j.
