.NET Core Microservices - Use Queue for Checkout Message

The video tutorial demonstrates how to transition from using a topic and subscription model to a simple queue model in an application. It covers the process of creating a basic queue, testing the application by placing a new order, and configuring the consumer to listen to the queue instead of a topic. The tutorial also explains how to set up a processor for the checkout queue and includes debugging steps to ensure the application functions correctly. The video concludes by highlighting the minimal code changes required for this transition.

What happens when a new order is placed but not recorded in the database?

• The order is lost permanently.

• The order is stored in a temporary file.

• The order is pushed to a queue without a consumer.

• The order is sent to a backup server.

What change is necessary to make the consumer listen to a queue instead of a topic?

• Update the database schema.

• Modify the application settings to use the queue name.

• Install a new software package.

• Change the server configuration.

Where is the consumer for the queue configured in the application?

• In the database settings.

• Inside the Azure service bus consumer in the order API.

• In the network configuration files.

• In the user interface settings.

What is the purpose of adding a debugging point in the code?

• To verify that the message is processed correctly.

• To change the message format.

• To delete unnecessary data.

• To increase the speed of message processing.

What is the main advantage of switching from a topic to a queue?

• It reduces the cost of message processing.

• It allows for multiple consumers to process the same message.

• It simplifies the message processing logic.

• It requires no changes in the code.
