trovares-connector 2.6.2

Connecting the Trovares xGT graph analytics engine to other applications.

trovares_connector Package

This Python package is for connecting the Trovares xGT graph analytics engine to other applications. Trovares xGT can significantly speedup Neo4j queries.

The default connector provided is for Neo4j or AuraDB. The package also provides an optional ODBC connector for connecting to databases or applications that support ODBC. Information about the ODBC connector can be found in the documentation.

Requirements

• Neo4j Python
• xGT Python
• Pyarrow
• Trovares xGT

Installation

You can install this python package by executing this command:

python -m pip install trovares_connector

If you want to use the ODBC connector, you can install the optional dependencies like so:

python -m pip install 'trovares_connector[odbc]'

If you don't have Trovares xGT, you can install and run the Developer version from Docker:

docker pull trovares/xgt
docker run --publish=4367:4367 trovares/xgt

Using the trovares_connector

From any Python environment, simply importing both xgt and trovares_connector is all that is needed to operate this connector.

A simple example below shows connecting to Neo4j and xGT, transferring the whole graph database to xGT, running a query in xGT, and printing the results:

import xgt
from trovares_connector import Neo4jConnector, Neo4jDriver

# Connect to xGT and Neo4j.
xgt_server = xgt.Connection()
xgt_server.set_default_namespace('neo4j')
neo4j_server = Neo4jDriver(auth=('neo4j', 'foo'))
conn = Neo4jConnector(xgt_server, neo4j_server)

# Transfer the whole graph.
conn.transfer_to_xgt()

# Run the query.
query = "match(a:foo) return a"
job = xgt_server.run_job(query)

# Print results.
print("Results: ")
for row in job.get_data():
    print(row)
