Processor for Neo4j 4.0

[Martin Ebert <ma...@gmail.com>]

Hi community,
among the bundles is the fantastic Graph Bundle
https://github.com/apache/nifi/tree/master/nifi-nar-bundles/nifi-graph-bundle

There are two questions I would like to ask:

1. The ExecuteCypher processor works wonderfully with Neo4j version 3.x  Is
anyone working on an update to make 4.0 work?

2. Has anyone ever thought about a possibility (e.g. extra processor or
extension of the above) to take the data (json, Parquet, CSV) as FlowFile
Content to be able to create or update nodes and relationships directly
from it?

Greeting,
Martin

Also, glad to see you're getting value out of that processor. If you're
feeling adventurous, I created a new Gremlin bytecode driver here:
https://github.com/MikeThomsen/nifi-gremlin-bytecode-client-service

It's also under review as a PR onto NiFi. The current Gremlin driver uses
script submission; this one does full client-side API work with the Gremlin
bytecode API. A colleague of mine is using a fork of it that he's tweaked
and found it to be very fast against JanusGraph.

Martin,

Unless they changed the behavior of the driver, it should be a matter of
adding a build profile to swap in the 4.X driver.

With regard to a Record API processor, the answer is yes. Can't go into
more detail than that at the moment, but I hope to be able to go into more
detail later this year.
