You can find official documentation here. DynamoDB can scale to any level while keeping response time in milliseconds. First, we will create two Java files CdkDeployApp.java and CdkDeployStack.java in the main project directory for Java code in the app. Output in the. mkdir cdkTrainer && cd cdkTrainer We will use cdk init to create a new Python CDK project: cdk init app --language python Once created, you should see a bunch of output. We need to pass the name and type of partition key. Our entire stack is configured and deployed using CDK. Then we will create a cdk.json and cdk.context.json file in the root. To generate a sample project in Python, run the command below: cdk init sample-app -language python. Sample. Modular package of AWS SDK V3 increase lambda performance (reduced cold start and faster execution time) First class typescript support to reduce common errors Plus lambda now supports 1ms billing so this is great time to make use of lambda for dynamodb operations. You can either install the complete AWS CDK or only install the AWS CDK for the DynamoDB client. So we decided to create multiple DynamoDB tables to store the JSON data that Mary sent to us, and since the code will be more complex, We can start splitting the code and create some CDK.
