From Tower of Babel to Babel Fish | Voxxed Days Thessaloniki 2025

You’ve conquered the basics – Kafka clusters are running, producers are producing, and consumers are consuming. Life is good…until your Python team needs to talk to your Java services, and suddenly, everyone’s speaking different languages. Like the biblical Tower of Babel, your elegant event-driven architecture crumbles under the weight of miscommunication.
What if there was a Babel Fish for your distributed systems? A way to let each service speak its native tongue while ensuring perfect understanding across your entire ecosystem?
This talk will explore how Schema Registry transforms from “that optional component you skipped” into the essential backbone of resilient, polyglot Kafka architectures. You’ll discover practical strategies for implementing data contracts that evolve without breaking, patterns for seamlessly integrating Schema Registry into your CI/CD pipelines, and real-world approaches for managing schema evolution without derailing your development velocity.
Whether scaling beyond your first language, preparing for a multi-team Kafka implementation, or recovering from your first production schema disaster, you’ll leave with concrete techniques to make your Kafka systems more resilient, flexible, and ready for Day 2 challenges.
