AWS Serverless Microservices with Patterns and Best Practices - Developing getAllProducts Methods for Product Lambda Mic

The video tutorial covers the development of a 'get all products' method for a Lambda microservice using the AWS DynamoDB SDK for JavaScript. It explains the use of the scan command to retrieve all items from a DynamoDB table, detailing the implementation process, including setting up parameters and handling environment variables. The tutorial also highlights the differences between the scan command and the get item command, emphasizing the importance of importing necessary packages and verifying the setup.

What is the primary purpose of the 'get all products' method in the context of the video?

• To create new product entries in the database

• To retrieve all product records from the DynamoDB table

• To delete all products from the database

• To update product details in the database

Which command is used to retrieve all items from a DynamoDB table?

• Put Item Command

• Scan Command

• Get Item Command

• Delete Item Command

What is the key parameter required for the SCAN command?

• Item ID

• Attribute Value

• Table Name

• Partition Key

How are environment variables used in the 'get all products' method?

• To pass the table name to the SCAN command

• To configure network settings

• To store user credentials

• To define API endpoints

What is the role of the DynamoDB client send method in the implementation?

• To update the client configuration

• To log errors in the application

• To send the SCAN command to the DynamoDB service

• To receive data from the client

How does the 'get all products' method differ from the 'get product' method?

• It requires an ID parameter

• It uses the SCAN command instead of the Get Item Command

• It updates product information

• It deletes product entries

What is the main similarity between the 'get all products' and 'get product' methods?

• Both require a table name

• Both use the Delete Item Command

• Both update the product table

• Both require user authentication
