Kafka for Developers - Data Contracts Using Schema Registry - Build the PUT Endpoint for the CoffeeOrderService - PUT /c

This lecture covers building an update endpoint for a coffee order service using Spring Kafka. It explains creating a PUT endpoint in the coffee order controller, implementing the update function, and configuring producer and consumer for Kafka topics. The video also includes testing the application and troubleshooting common issues, ensuring the system can handle multiple event types in a Kafka topic.

What is the primary purpose of the PUT endpoint in the coffee order service?

• To manage database transactions

What strategy is used to allow multiple event types in the same Kafka topic?

• Record Name Strategy

• Event Type Strategy

• Topic Name Strategy

• Schema Name Strategy

What is the purpose of restarting the consumer application during testing?

• To update the user interface

• To reset the database

• To clear the logs

• To apply new configurations

What error was encountered during the testing phase?

• Authentication error

• Database connection failure

• Schema incompatibility

• Network timeout

What is the expected HTTP status code for a successful PUT request?

• 403

• 404
