My name is Michael Simons and I work as software engineer for Neo4j. Neo4j is the creator of the Graph database with the same name. The main focus of my work is our object mapping framework (Neo4j-OGM) and Spring Data Neo4j. You can find my personal blog under info.michael-simons.eu and myself on Twitter as @rotnroll666.
With persistent network connections between things, the exceptional case should be expected and not considered to be a surprise. There are dozens of reasons why a remote connection may be closed or be rendered unusable. In such scenarios precautions must be taken so that your logic succeeds eventually.
Most database management systems (DBMS) these days provides client libraries aka drivers that provide stateful connections to the DBMS. Establishing such connections includes among other things acquiring a transport link, a network session on both the client and the server and of course, user authentication. These days connections are usually encrypted —…
For the impatient, here’s a complete, running example. You need to have
curl, Docker and Maven installed:
mkdir bootiful-music && cd bootiful-music
npm install -g generator-jhipster
curl -L https://r.neo4j.com/hipster-music -o bootiful-music.jh
jhipster import-jdl bootiful-music.jh
docker-compose -f src/main/docker/neo4j.yml up -d
Access the application at http://localhost:8080.
And now for the story behind it:
We are going to address three topics in this post, and they all deal with new features in Neo4j 4.0 and surrounding ecosystem. We have:
And, as a bonus: Fabric; a new way of querying multiple Neo4j databases together.
In this post, I use the super secret password that we’ll use in testing Neo4j SDN-RX as well. The secret password is for the user neo4j will be secret.
Neo4j offers the movie graph starter code sample through its browser…
I want to share some quick information on how to use Aura from your Java application. Aura provides Neo4j instances, similar to your local setup. You need to use the Neo4j Java Driver which implements the Bolt Protocol.
Aura is a secure cloud offering and transport between your hosts and Aura is of course encrypted. Aura uses SSL certificates to identify itself. Those certificates are validated certificates being part of a trust chain. Aura requires the connection to be encrypted.
The Neo4j Java Driver up to version 1.7.5 defaulted to…
Current state and future plans of Neo4j-OGM
There is happening so much right now in the world of graphs.
We have just released our first public milestone release of Neo4j 4.0, the upcoming major version of Neo4j, next week the NODES2019 online conference is happening and the team behind Spring Data Neo4j and Neo4j-OGM wasn’t sleeping as well:
SDN/RX was released as a public beta with a fantastic introduction video by Gerrit Meier.
I personally was super happy to find a blog post written by someone else about SDN/RX title “Reactive programming with Neo4j”. …
I work for Neo4j, where I’m mainly responsible for maintaining Neo4j-OGM, our object graph mapper, and Spring Data Neo4j, our implementation of the Spring Data repository abstraction. While this current work is mostly graph related, I also worked and I am still working with relational databases, too.
During the last months I noticed that some issues that I encountered in the context of object relational mapping, keeps reappearing in object graph mapping, most of the time with similar consequences.
Today I’m focus on one of those things: Identifiers.
I’ll use the wording database entities when I speak about things that…
There are several aspects that needs to be considered while making the decision for or against a certain test setup.
It has been nearly a year since our last post about the things happening with Neo4j in the “Spring World”. Time did not stand still and the Spring Data Neo4j / Neo4j-OGM Team has been working on improvements and building new features based on the foundations laid out with SDN 5.0 and Neo4j-OGM 3.0 last year.
My name is Michael Simons, I am a Java Champion and the author of the German book about Spring Boot 2 and Spring 5. I joined the Spring Data Neo4j team in July 2018. Together with Gerrit Meier I have been working on the…
