The blog post explores how DeltaStream facilitates seamless integration with various data serialization formats such as JSON, Protocol Buffers, and Apache Avro, simplifying the process of creating real-time analytics dashboards. The example provided illustrates an eCommerce scenario where transactional data in Protobuf and customer data in Avro are converted into JSON format for a dashboard. Key metrics include real-time revenue sums and geographic transaction counts. DeltaStream handles the complexities of serialization and deserialization behind the scenes, allowing users to focus on writing SQL queries for data transformation and integration. The post also highlights the use of DeltaStream descriptors and schema registries to manage data formats effectively, demonstrating how these tools streamline the development of pipelines for real-time insights without the burden of managing complex streaming applications.
