Speaker: Michael Hunger, Senior Director, User Innovation, Neo4j Session type: Full Length Abstract: Cypher is a great, powerful query language, enabling you to quickly get the most from your graph queries. For some, squeezing out every bit of performance is necessary, and you wish you had the capability to do so packed into a reusable LEGO block for your queries. In this session, you’ll learn from practical examples of how to build user-defined procedures, functions, and aggregation functions with just a few lines of Java code. We’ll dive into how to efficiently use the Java API and what to watch out for to ensure you get the most out of your work. This will help you to build your own extensions to Neo4j or understand better how the existing procedures and functions work under the hood.
