In this video, you'll learn how to build a robust exception handling system for Azure Cosmos DB operations that scales from single CRUD operations to complex batch processing. Instead of writing try/catch blocks in every FastAPI route, we'll create a centralized system that automatically converts database errors into meaningful business exceptions.

What You'll Learn:
Custom exception classes that map to HTTP status codes
Exception translation layer for Azure Cosmos DB errors
Centralized FastAPI exception handlers
How to handle both single and batch operation failures
Extracting useful diagnostics (activity ID, request charge, latency)
KQL queries for debugging production errors
