Getting started with @EmbeddedKafka and Spring Kafka auto-configuration in a @SpringBootTest made working together despite mismatching defaults by adjusting bootstrapServersProperty

In Event-driven architecture there are unique identifiers everywhere: at entity level, at event level, at process level etc. In this blog post, I will show you a de facto standard for how you could easily generate, persist, serialize and deserialize IDs natively through Kafka, Java and JPA.
