    Hello Valentine Serebreanu,

    Good day!

    Thank you for your valuable feedback!

    We sincerely apologize for the confusion caused by the original question. As you correctly pointed out, DAX is unsuitable for this scenario, as it is specifically designed to accelerate Amazon DynamoDB queries and not improve RDS-based workloads. The question aimed to focus on improving the Lambda function’s response time most cost-effectively without touching the underlying RDS database.

    You are right that ElastiCache could have been a more effective solution for caching, as it supports caching results for faster retrieval across multiple Lambda invocations. However, the question was deliberately focused on how Lambda itself could be optimized without introducing other services like ElastiCache that could increase complexity or cost. We intentionally avoided database optimizations and additional managed services to keep the solution as cost-effective as possible.

    We have corrected the question to reflect the proper context and options. Again, we appreciate your detailed feedback and hope this resolves the confusion!

    Regards,

    Neil @ tutorials dojo
