AWS Serverless Microservices with Patterns and Best Practices - Creating Custom Queue Construct for AWS SQS with AWS CDK

The video tutorial covers the creation and implementation of a custom queue construct for Amazon SQS using the AWS CDK. It explains the design process, including defining interfaces and properties, setting up event sources, and configuring batch sizes. The tutorial also discusses the integration of Lambda functions and the necessary permissions for event source mapping.

What is the primary purpose of creating a custom queue construct in the CDK project?

• To enhance the graphical user interface

• To manage database connections

• To tailor the queue to specific use cases

• To improve network security

Which property is essential for the custom queue to interact with the ordering microservices?

• Visibility timeout

• Event source

• Consumer function

• Queue name

What is the role of the 'I function' in the custom queue construct?

• To manage the queue's security settings

• To set the queue's name

• To specify the consumer function as a Lambda function

• To define the queue's visibility timeout

What is the significance of setting a public property for the queue?

• It reduces the queue's visibility timeout

• It allows the queue to be accessed by other services

• It increases the queue's processing speed

• It enhances the queue's security

Why is the batch size set to 1 in the custom queue construct?

• To process multiple messages simultaneously

• To enhance the queue's security

• To increase the queue's visibility timeout

• To receive one message at a time

What is the default batch size for Lambda functions receiving messages from Amazon SQS?

• 1

• 5

• 10

• 20

Which method is used in CDK to handle permissions for event source mapping?

• addEventSource

• setPermissions

• configureSource

• manageAccess

What is the purpose of the event source mapping in the custom queue construct?

• To manage the queue's security settings

• To map events from the queue to the consumer function

• To define the queue's visibility timeout

• To set the queue's name

Which AWS service is targeted by the custom queue as a consumer?

• Amazon S3

• Amazon Lambda

• Amazon EC2

• Amazon RDS

What is the main benefit of using a custom construct in a CDK application?

• It enhances the graphical user interface

• It improves network security

• It allows for more flexible and reusable infrastructure

• It simplifies the deployment process
