How can a developer address the HTTP 429 Too Many Requests error from a third-party API in an application where Amazon SQS triggers a Lambda function for message processing, especially after an increase in usage?
Explanation:
The correct answer is D. Configuring maximum concurrency on the SQS event source ensures that the Lambda function does not exceed the rate limits of the third-party service, thereby preventing the HTTP 429 Too Many Requests error. By controlling the number of concurrent executions of the Lambda function, you can manage the rate at which the function makes API calls to the third-party service, aligning with its capacity and reducing errors.
