Photo credit I recently had the opportunity to play with the Cypher DSL (domain-specific language) library, and I found it difficult to figure out syntax for some of the queries I was trying to construct. This blog post will hopefully help you understand how to construct your own programmatic queries with Cypher DSL by showing you syntax for nodes, relationships, and filtering. Then see how this in action with some examples for assembling those components into full queries translated from common clauses, functions, and result formats in Cypher.

Photo credit Just when I’m feeling pretty confident about my git skills, I run into a scenario like this one that backpedals my confidence. I keep learning, though, and small improvements are still progress. :) A few weeks ago, I was working on an update to the Graphacademy Spring Data Neo4j course, and things got out of sync. Before I knew it, I was stuck in merge conflict hell and wondering how I got there and if/how I could ever get out.

Photo credit After working on a new online Spring Data Neo4j course, I learned a couple more things about updating an entity. The course required a different set of scenarios than outlined in my previous SDN update blog post, so I wanted to cover those scenarios, as well. Spring save() method First up is the out-of-the-box save() method that is provided by Spring as a default. This method takes an input of the entity object you want to save to the database.

Photo credit The NODES 2024 conference is approaching fast, and we have a lot of exciting activities, including talks, workshops, and more. Here’s what you need to know to get ready for NODES 2024. What is NODES? NODES is a free, virtual conference run by Neo4j for developers, data scientists, and other technical roles who want to learn more about graph databases and how they can be used to solve complex problems.

Photo credit Every year, Neo4j hosts the virtual event NODES 2024 - a free, technical event spanning global timezones and a variety of graph-related topics. This is one of my favorite events of the year, but it doesn’t happen without countless hours of planning and work to make it valuable to the graph community. This year, my colleague and I were put in charge of organizing the schedule, determining how sessions are lined up between the start and end time of the event.

Photo credit Migrating an application always feels a bit daunting, and that was the way I felt when I looked at the Spring AI 1.0 milestone release. However, the upgrade didn’t make as many major shifts as anticipated. This guide will help you upgrade your Spring AI application from version 0.8 to 1.0 and explain why each change is needed. Changes include some naming shifts, configuration options, and more.

Photo credit For an upcoming event, I was asked to give a demo of how to run Neo4j on Kubernetes. I had very little experience with Kubernetes, so I decided to document my journey for later reference. What is Kubernetes? Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation.

Photo credit There are so many options when it comes to languages, frameworks, and tools for building generative AI (GenAI) applications. When you are just getting started, these decisions and figuring out how to integrate everything can be overwhelming. My team has been working on some pre-packaged solutions to make this process easier by providing starter kit projects with a few key technologies. One of those is the topic of today’s post - building a GenAI application with Spring AI in Java.

Photo credit There is no shortage of technical events such as conferences, meetups, trainings, hackathons, and so on. These events are a great way to learn new things, connect with people, and share knowledge with others. One of the most valuable and exciting ways to share knowledge is by giving a technical presentation. Today, we will look at how to submit a technical presentation for an event and get some personal recommendations from me, as well.
