DeltaStream is a robust platform designed to unify, process, and govern streaming data, serving as both a streaming analytics platform and a streaming database, particularly effective in handling the demands of IoT data. Leveraging Apache Flink, DeltaStream offers a fully managed solution capable of processing streaming data with low latencies, making it suitable for real-time applications across diverse sectors such as transportation, healthcare, and security. The text provides two illustrative use cases involving transportation sensor data to highlight DeltaStream's capabilities. The first use case demonstrates the use of Materialized Views to power a real-time dashboard for monitoring truck fleets by enriching truck information with temperature sensor data. The second use case outlines the creation of a real-time alerting pipeline that can trigger alerts if a truck's temperature exceeds a certain threshold, showcasing DeltaStream’s ability to support real-time stateful transformations and alerting services. Additionally, the text emphasizes the importance of using streaming storage systems like Apache Kafka and processing technologies such as Apache Flink to meet the low latency and scalability requirements inherent in IoT applications, underscoring DeltaStream's pivotal role in managing the complexities of IoT data.
