Motivation
JanusGraph is the first Apache Tinkerpop graph database i could work with Gremlin Python.
pyjanusgraph shall make it easier to work with JanusGraph from Python
Installation
pip install -i https://test.pypi.org/simple/ pyjanusgraph==0.0.1a2
Usage
First start your janusgraph server e.g. by using the docker command:
docker run --name jg -it -p 8182:8182 --mount source=/$HOME/graphdata,target=/graphdata,type=bind janusgraph/janusgraph
RemoteGremlin
The RemoteGremlin class provides a simplified API to work with a remote Gremlin Server connection to JanusGraph. Optionally you may share data with an e.g docker based Server by setting up a sharepoint.
accessing a remote graph
from tp.gremlin import RemoteGremlin
import os
rg = RemoteGremlin()
g=rg.open()
vList = g.V().toList()
print ("found %d vertices" % (len(vList)))
rg.close()
sharing data
from tp.gremlin import RemoteGremlin
import os
rg = RemoteGremlin()
rg.setSharepoint(os.path.expanduser("~/graphdata"), "/graphdata/")
g=rg.open()
graphmlFile = "air-routes-small.xml";
shared = rg.share(graphmlPath)
g.io(shared).read().iterate()
vCount = g.V().count().next()
print ("%s has %d vertices" % (shared, vCount))
rg.close()
