Summer is the perfect time to relax in the shade and enjoy inspiring talks about graphs from GraphConnect! We’ve just published the developer and data science presentations with business cases and in-depth tech talks. Don’t hesitate to take a look; a sign-in is required. As you plan for the Fall, save the date for the Neo4j NODES conference, November 16th and 17, 2022. You still have time to submit your talk until August 20.
This week’s newsletter features an interesting array of articles for your enjoyment! In the Journeys in Java, you will learn how to build a Spring Boot application with a couple of REST endpoints to access the data from a Neo4j database. You also won’t want to miss Graph Data Science for User Segmentation, where Tomaz Bratanic applies the Neo4j GDS library to identify node roles.
Cheers,
Yolande Poirier
PS: Don’t miss the Neo4j Code Golf challenge, a Cypher coding contest with prizes totaling $27,000! Start golfing and have fun!

… Of Special Interest
- In just one minute, you can start a DevSpace, pull the #neo4j docker image & run it, open the web interface, run a py script to add data, and run Cypher query to visualize. Check out the repo!
- Adding the org.neo4j.procedure : apoc-processor maven dependency to the pom.xml file with your favorite Java IDE Learn more on MavenLibs.
- apoc.cypher.runFirstColumn is used by older versions of the Neo4j #GraphQL library to run subqueries and can be useful when you need to query using dynamic labels or relationship types. Great tip!
