DeltaStream offers an efficient solution for businesses to track and manage their order shipments in real-time by utilizing SQL queries to join and filter data streams on Kafka topics. By creating streams for "Orders" and "Shipments" and performing an interval left join within a 30-minute window, businesses can identify orders that were not shipped in time. The process involves setting up a continuous interval join to detect unshipped or late shipments, allowing companies to promptly address issues and improve customer satisfaction. The application is designed to facilitate quick responses by alerting relevant teams about shipping discrepancies, thus maintaining brand integrity and enhancing operational efficiency. DeltaStream's capabilities are showcased through practical examples, with more use cases expected to be demonstrated in future content, inviting interested parties to request a demo for hands-on experience.
