Yoda Response: Optimized a real-time data processing solution using Python and AWS Lambda, I have. In a project for media sentiment analysis, we did. Faced challenges with performance, we did, due to the nature of Python. Overcame this by using asynchronous programming and optimizing code execution paths, we did. AWS Lambda functions, we used, for processing incoming data streams, which required high scalability. Leveraged AWS Lambda's auto-scaling capabilities, we did, to handle varying loads efficiently. Also, used environment variables to manage configurations dynamically, ensuring flexibility and scalability. Monitored performance using AWS CloudWatch, we did, and made adjustments as needed to maintain optimal performance.
