Kafka for Developers - Data Contracts Using Schema Registry - Let's Build AVRO Kafka Producer

This lecture covers building a Kafka producer to publish Avro records without a schema registry. It explains setting up a producer using Gradle, configuring broker properties, creating Avro records, and sending them to a Kafka topic. The session also includes setting up logging with SLF4J and Logback, and testing the Kafka setup using Docker.
