GIE for Cypher#
We have implemented Neo4j’s Bolt protocol for you to connect your Neo4j applications to the GIE’s Frontend service.
Your first step is to obtain the Cypher endpoint for the Bolt connector
Follow the instruction while deploying GIE in a K8s cluster,
Follow the instruction while starting GIE on a local machine.
Connecting via Python Driver#
GIE makes it easy to connect to a loaded graph with Neo4j’s [Python Driver]](https://pypi.org/project/neo4j/).
You first install the dependency:
pip3 install neo4j
Then connect to the service and run queries:
from neo4j import GraphDatabase, RoutingControl URI = "neo4j://localhost:7687" # neo4j:// + Cypher endpoint you've obtained AUTH = ("", "") # We have not implemented authentication yet def print_top_10(driver): records, _, _ = driver.execute_query( "MATCH (n) RETURN n Limit 10", routing_=RoutingControl.READ, ) for record in records: print(record["n"]) with GraphDatabase.driver(URI, auth=AUTH) as driver: print_top_10(driver)
A simpler option is to use the
interactive object for submitting Cypher queries through
GraphScope’s python SDK, which is a wrapper that encompasses Neo4j’s
Python Driver and will automatically acquire the endpoint.
Connecting via Cypher-Shell#
Download and extract
wget https://dist.neo4j.org/cypher-shell/cypher-shell-4.4.19.zip unzip cypher-shell-4.4.19.zip && cd cypher-shell
Connect to the Bolt connector with the Cypher endpoint you’ve obtained
./cypher-shell -a neo4j://localhost:7687
@neo4j> Match (n) Return n Limit 10;
