Welcome to This Week in Neo4j where I share the most interesting things I found in our community over the last seven days.

This week Will and I interviewed Ward Cunningham as part of the Neo4j online meetup and we launched the first version of the much awaited Kafka Connector. Neo4j 3.5 was also released and Jennifer kicked off an exciting series of posts on the Marvel Universe.

Michael travelled to Krakow this week and presented How Graph Databases efficiently store, manage and query connected data at scale at the CoreDump conference. Don’t forget to say hi if you see us at any events you’re attending.


This weeks featured community member is Tom Michiels, Data-architect/scientist at Vectr.Consulting

Online Meetup: Iterative modeling of corporate resources in a rapidly growing company


In last week’s online meetup, Ward Cunningham showed off El Dorado – a tool he’s built to collect metadata from all aspects of NewRelic’s operations to build a graph based structure warehouse.



Ward has also setup a version of the tool running on a dummy dataset if you want to see how it works in more detail.

New Neo4j Integration with Kafka


One of the most common requests that we’ve received in recent years is an integration with Apache Kafka, and this week we released the first version of this integration.

The Kafka Producer communicates data from Neo4j’s event listener to a Kafka topic, and on the Consumer side you can specify a piece of Cypher that will execute every time a message is received on a Kafka topic.

Create a Data Marvel : The Data Model


Jennifer Reif has started a series of blog posts in which she’ll show how to build a full stack application with Spring and Neo4j based on the Marvel dataset.

In the first post Jennifer evaluates Marvel’s API, and then comes up with an initial graph data model after several whiteboard sessions.

kNN: Classification of members of congress using similarity algorithms


Tomaz Bratanic has written a blog post showing how to use Neo4j’s similarity algorithms as part of a k-Nearest Neighbours classification algorithm to work out how members of congress are likely to vote.

Tomaz explains how to use the similarity algorithms to find each node’s top k neighbours, and then select the majority class from those neighbours as the predicted class.

Neo4j 3.5 was released this week, and Michael has written a quick post on the community site explaining some of the features that will make your lives easier.

This release contains support for full text search, indexed backed order by queries, Off-heap transaction state, compiled expressions, and more.
