What is distributed tracing for performance?

It's tagging requests with a unique ID to track latency across services, revealing hidden bottlenecks averages miss.

How do you implement trace IDs in Python?

Grab from headers in Flask before_request, generate UUID if missing, propagate to DB/external calls via logs/headers.

They often eat 50%+ of latency without alerting — users feel every ms.

Sluggish apps? It's not your database—it's the shadows between services. Distributed tracing turns invisible delays into actionable fixes.
