Struggled with the complexity of designing Kafka Streams applications? Without sufficient up-front architecture work, it�s all too easy to stumble into misunderstandings, rework, or outright failure. Although standards like UML and C4 model have guided software designs for years, stream processing has lacked a visual framework - until now. KSTD (Kafka Streams Topology Design) introduces an open standard and component library for describing and visualising Kafka Stream Topologies with Excalidraw. Simple principles ensure teams can keep diagrams simple yet include important details, build trust in their designs, and streamline the development lifecycle. You will learn how standardised diagrams support team alignment, and how KSTD fosters consistent and clear communication for Kafka Streams. Design up-front, avoid mistakes, save time, and build trust.
