A company has an online shop that uses an Amazon API Gateway API, AWS Lambda functions, and an Amazon DynamoDB table provisioned with 900 RCUs. The API Gateway API receives requests from customers, and the Lambda functions handle the requests. Some of the Lambda functions read data from the DynamoDB table. During peak hours, customers are reporting timeout errors and slow performance. An investigation reveals that the Lambda functions that read the DynamoDB table occasionally time out. Amazon CloudWatch metrics show that the peak usage of the DynamoDB table is just below 900 RCUs. Which solution will resolve this issue MOST cost-effectively?
