Over the 2023 holidays, I wanted to learn more about GeoParquet and learn more about geospatial data in general. I decided to create a simple Neo4j plugin that reads in a Geoparquet file (or any parquet file for that matter) and return the results to the user. This is similar to the capability in the […]
Geospatial use cases with Neo4j are interesting. A colleague recently asked if there was a way to identify which pieces of property a power line might intersect. Thinking back to previous work on H3 and Neo4j, I knew we could model the power line as a set of hex addresses and model the property geometry […]
In this blog post, we are going to run through some simple queries to show how to query and traverse the graph. We are going to focus on the geospatial database for now. The next blog post will discuss using the Neo4j 5 Composite Database for the distributed queries. Data Model As a quick refresher […]
A couple of weeks ago, I was asked how to configure Neo4j to use JAAS with Kafka using SASL_Plaintext. While the Neo4j documentation does talk about SSL configuration, it doesn’t specifically discuss JAAS. On the Kafka side, I used a Bitnami AMI (Kafka – AMI ID bitnami-kafka-2.3.0-0-linux-debian-9-x86_64-hvm-ebs-nami (ami-0ca61ab6a3b990db7)) running on AWS. There were some configuration […]
While Neo4j 4.0 was released in December 2019, the Neo4j 4.0 python driver wasn’t ready to be released at that time. In the last week or so, Neo4j released a 4.0.0a4 version of the driver that allows for multi-database support. The driver documentation has been updated to show how to use the latest driver. Someone […]
This blogpost provides guidance to configure SSL security between Kafka and Neo4j. This will provide data encryption between Kafka and Neo4j. This does not address ACL confguration inside of KAFKA. Self Signed Certificates This section came from https://medium.com/talking-tech-all-around/how-to-enable-and-verify-client-authentication-in-kafka-21e936e670e8Make sure that you have truststore and keystore JKSs for each server.+ In case you want a self signed […]
This blog post is mostly for my benefit and for the ability to go back and remember work that I have done. With that being said, this blog post talks about the Neo4j Spark Connector that allows a user to write from a Spark Data Frame to a Neo4j database. I will show the configuration […]
With the upcoming Neo4j 4.0 release, it was time to revisit deploying a Neo4j causal cluster via Docker. Our fantastic parter, GraphAware published a quickstart for deploying a cluster in Docker. Docker is a tool designed to make it easy to create, deploy, and run applications by using containers. Containers allow developers to package an […]
In Part 1, we configured Neo4j, Kafka and MySQL to talk using the Neo4j Kafka plugin and Maxwell’s Daemon. In part 2, I will show how data can be added into MySQL and then added/modified/deleted in Neo4j through the Kafka connector. For our dataset, I chose the Musicbrainz dataset. This dataset has several tables and […]
With the new Neo4j Kafka streams now available, there has been a few articles such as A New Neo4j Integration with Apache Kafka and How to leverage Neo4j Streams and build a just-in-time data warehouse and Processing Neo4j Transaction Events with KSQL and Kafka Streams and finally How to embrace event-driven graph analytics using Neo4j and Apache […]
