Connection to Neo4J possible ?

KNIME Analytics Platform

Hi,

I would like to know if it's possible to connect Knime to the graph database Neo4j ? And if it's possible, how could I do the connection ?

Thanks,

Chris

Hi Chris,

currently KNIME does not support to connect to a Neo4j graph db. However we plan to add Neo4J support in the future via the Bueprints API. Any comments or thoughts about the integration of Neo4J or Blueprints are highly welcome.

Bye,

Tobias

Thanks in advance

Hello iiiaaa,

Not as far as I know, but you can use the REST nodes for KNIME to push data back and forth between KNIME and Neo4J.

Hi iiiaaa

We have used version Neo4j-2.3.2 Version of the jdbc driver (https://github.com/neo4j-contrib/neo4j-jdbc-2x) and connect using the database read to execute Cypher scripts instead of SQL. This works with Neo4j version 3. 

There is a newer version of the driver which we have not tried.

You can do it with version 3.1.0 of the driver (https://github.com/neo4j-contrib/neo4j-jdbc/releases), but the 3.0 throws an error returning any rows (see https://github.com/neo4j-contrib/neo4j-jdbc/issues/60 for details).

Hello!

as @mauuuuu5 said there are dedicated nodes to connect and read from/write to Neo4J DB.
See here: https://www.knime.com/whats-new-in-knime-42#neo4j
