Disclaimer: In most cases, we don’t recommend editing files in a container. However, in rare cases, you might need to reproduce and slightly modify a file in a production container, especially when debugging. (In this case, the vim method I’m using works on Fedora 32 on my laptop and it is the base of my Red Hat OpenShift container image.)

Debezium serialization with Apache Avro and Apicurio Registry

By Hugo Guerrero December 11, 2020December 9, 2020

In this article, you will learn how to use Debezium with Apache Avro and Apicurio Registry to efficiently monitor change events in a MySQL database. We will set up and run a demonstration using Apache Avro rather than the default JSON converter for Debezium serialization. We will use Apache Avro with the Apicurio service registry to externalize Debezium’s event data schema and reduce the payload of captured events.
