Session Overview

Learn how to test and validate Kafka’s consistency and availability guarantees using autonomous testing with Antithesis. Discover how Kafka’s KRaft protocol enables configurable trade-offs between strong consistency and high availability.

When chaos hits production, which do you choose — strong consistency or high availability? Every distributed system faces this trade-off, but not every system truly knows how it behaves under stress.

In this session, learn how to verify your Kafka guarantees using autonomous testing with the Antithesis platform. We’ll explore how the latest Kafka architecture, powered by the KRaft protocol, can be configured to guarantee either consistency or availability — and how to test whether those guarantees actually hold.

You’ll learn how to:

  • Define consistency and availability as measurable system properties
  • Use autonomous testing to validate real-world behaviors under failure conditions
  • Understand how Kafka’s KRaft protocol impacts system guarantees
  • Compare autonomous vs. traditional example-based testing approaches

By the end, you’ll have a practical framework for defining, testing, and validating guarantees in Kafka-compatible systems — so you can confidently say your guarantees are actually guaranteed.
