Title of Talk:
How Do You Architect a Kafka Streams Topology?

Abstract:
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 its own 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 design 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.

Title of Talk:
Kroxylicious, the snappy open-source proxy for Apache Kafka

Abstract:
Proxies are a powerful architectural pattern commonly used in other application-layer protocols like HTTP, but they remain underutilized in the Kafka ecosystem. Kroxylicious is a groundbreaking, early-stage project that aims to change this by making it easier to develop Kafka proxies with minimal effort. While some organizations have built their own Kafka-aware proxies to address specific challenges, these solutions often remain closed-source and highly specialized. Kroxylicious tackles this problem by offering a set of pre-built capabilities and common features out-of-the-box, enabling developers to concentrate on the custom logic their applications need. In this session, I will introduce Kroxylicious, highlight its potential use cases, and demonstrate how it can simplify Kafka proxy development, reduce complexity, and unlock new possibilities for real-time data processing.
