Toolbelt Trifecta: Connecting to Neo4j with Java and AWS Lambda

The author of this article is a Developer Relations Engineer at Neo4j, who created a Java-based AWS Lambda function that connects to a Neo4j graph database and executes a query. The function uses the Neo4j Java driver to connect to a free cloud instance of Neo4j AuraDB, which contains a movie dataset. The author followed the instructions from an existing Neo4j Java example application and adapted it for use with AWS Lambda. They used JSON files for input and output, copied/pasted code where possible, and made only minor customizations. The function successfully executed a query that retrieves a person's name from the database and returned the result in a formatted JSON file. The author provides resources for further learning, including a GitHub project, an AWS Lambda example app, and Neo4j documentation.
