The text discusses the challenges of data governance in modern businesses, where data flows across different layers of an organization's application and data stack without proper controls and visibility. Apache Kafka is presented as a central nervous system for real-time data, connecting, storing, and analyzing continuous streams of data. Confluent's Stream Lineage tool is introduced to address the lack of data visibility in Kafka and event-driven architectures, providing an interactive map of all data flows that enable users to visualize and track critical data flows across their organization immediately as they occur. The tool allows users to navigate the flow of data, inspect and learn more about producers, consumers, or topics, and troubleshoot issues quickly. Stream Lineage is demonstrated through example scenarios, showcasing its ability to help developers build and visualize data pipelines, identify issues, and support audits and compliance questionnaires.
