    This AWS Solutions Konstruk implements a pattern Amazon DynamoDB table with stream to invoke the AWS Lambda function with the least privileged permissions.

    Here is a minimal deployable pattern definition:

    const { DynamoDBStreamToLambdaProps,  DynamoDBStreamToLambda} = require('@aws-solutions-konstruk/aws-dynamodb-stream-lambda');
    
    const props: DynamoDBStreamToLambdaProps = {
        deployLambda: true,
        lambdaFunctionProps: {
            code: lambda.Code.asset(`${__dirname}/lambda`),
            runtime: lambda.Runtime.NODEJS_12_X,
            handler: 'index.handler'
        },
    };
    
    new DynamoDBStreamToLambda(stack, 'test-dynamodb-stream-lambda', props);
