Amazon is the uncontested leader in ecommerce delivery, but smaller retailers can use graph technology to take back the lead. Ecommerce delivery service routing requires visibility into inventory and transit networks, as well as support for complex routing queries at scale with fast performance. Graph databases like Neo4j are well-suited for this task due to their ability to handle highly connected data and optimize routes based on various factors such as time of year and product type. A case study of eBay's use of Neo4j shows that the platform was able to overcome scalability challenges and improve delivery times, demonstrating the potential of graph technology in ecommerce delivery.
