What this sample helps you learn

Highlights
- First, in this README we'll demonstrate how to migrate a simple Apache Kafka application (kafka-app) to Oracle AI Database TxEventQ (kafka-app-step-1)
- Next, in the Using Oracle JSON (OSON) section we'll add support for Oracle's optimized binary JSON format, OSON, to the app (kafka-app-step-2).
- Finally, in the Transactional Messaging section, we further enhance the app to add transactional messaging to the consumer, so that database operations are handled using the same connection the consumer uses to receive messages (kafka-app-step-3).
