Cold Start Optimizer

Overview:

The system reduces Lambda cold start latency and stabilizes performance by minimizing initialization overhead and reusing resources across invocations.

Prerequisites:

• Deployed Lambda function
• Structured logging in place
• Baseline performance metrics available

Implementation/Steps:

1. The system initializes the Rekognition client at module scope.
2. The system minimizes imports and startup work.
3. The system keeps the deployment package lightweight.
4. The system logs initialization and execution timing metrics.
5. The system tracks cold start behavior across invocations.

Key Takeaways:

• Client reuse reduces repeated initialization cost.
• Minimal startup work improves latency.
• Timing metrics provide performance visibility.
• External contracts remain unchanged.
