The author of the article discusses the improvements made in Neo4j's Cypher query language, specifically focusing on two new features: COUNT{subquery} and Quantified Path Patterns (QPP). The author presents a case study using these features to detect transaction fraud rings, comparing their performance with an older version of Cypher. The results show that the newer version is significantly faster, even when dealing with complex patterns, such as 100-hop cycles. This improvement is attributed to the better expression and conciseness of Cypher in Neo4j 5, allowing for more efficient pattern matching and filtering. The author concludes that these features make Neo4j 5 a worthwhile upgrade, especially for analytical queries that can be refactored into real-time transactional ones.
