Connector with single-request transactions for Neo4j 3.0 and above

Project description

This library contains everything you need to execute single-request transactions for Neo4j 3.0 and above through its HTTP API.

Background

Research into the speed of performing ETL and batch-type actions on Neo4j showed that using a large, single-request transaction POST-request through Neo4j’s HTTP API outperforms other currently available libraries for this use-case (e.g. the official ‘neo4j-driver’ and ‘py2neo’). The goal of this connector is to provide convenience methods and classes that abstract away the boilerplate communication code.

Community thread about the difference in performance between drivers:

Example

import neo4j

connector = neo4j.Connector('http://localhost:7474', ('neo4j','neo4j'))
response = connector.run("""MATCH () RETURN COUNT(*) as node_count""")
first_row = response[0]
print(first_row['node_count'])
