Apache Avro is a data serialization system. It uses JSON for defining data types/protocols and serializes data in a compact binary format. In the following tutorial, we will configure, build and run an example in which we will send/receive an Avro message to/from Apache Kafka using Apache Avro, Spring Kafka, Spring Boot and Maven.
