Practical Change Data Streaming Use Cases With Apache Kafka and Debezium (QCon San Francisco 2019)

Practical Change Data Streaming Use Cases With Apache Kafka and Debezium (QCon San Francisco 2019)

Debezium (noun | de·be·zi·um | /dɪ:ˈbɪ:ziːəm/) - Secret Sauce for Change Data Capture

Apache Kafka is a highly popular option for asynchronous event propagation between microservices. Things get challenging though when adding a service’s database to the picture: How can you avoid inconsistencies between Kafka and the database?

Enter change data capture (CDC) and Debezium. By capturing changes from the log files of the database, Debezium gives you both reliable and consistent inter-service messaging via Kafka and instant read-your-own-write semantics for services themselves.

In this session you’ll see how to leverage CDC for reliable microservices integration, e.g. using the outbox pattern, as well as many other CDC applications, such as maintaining audit logs, automatically keeping your full-text search index in sync, and driving streaming queries. We’ll also discuss practical matters, e.g. HA set-ups, best practices for running Debezium in production on and off Kubernetes, and the many use cases enabled by Kafka Connect's single message transformations.
