Debezium enables real-time change data capture (CDC) by streaming database changes to downstream systems, making it a key building block for event-driven architectures. However, many teams use it without fully understanding how it behaves under the hood.

In this talk, we’ll take a practical look at Debezium using PostgreSQL as an example. We’ll cover how logical replication powers CDC, how Debezium captures and streams changes, and what happens during restarts or failures. The session will also highlight common pitfalls, operational best practices, and when Debezium is (and isn’t) the right choice.

Attendees will leave with a clear understanding of how Debezium works and how to use it effectively in real-world environments.
