This material is based on a talk I gave at SmartData 2025. I assume that you already know what CDC is and how Debezium works in general — if not, start with <a href="https://nryanov.com/postgresql/debezium-postgres/">PostgreSQL: Log-based CDC using debezium</a> and <a href="https://nryanov.com/kafka/kafka-connect-overview/">Kafka-connect: overview</a>.</p> <p>All examples below were tested with PostgreSQL 15, 16 and 17. If a version is not mentioned explicitly, PostgreSQL 17 is assumed. Examples are implemented using a runtime wrapper around Debezium Engine, but the same problems and solutions apply to the Kafka Connect connector, Debezium Server, and other deployment options.</p>
