Azure Cosmos DB Python Basics: Client Configuration and Dependency Injection with FastAPI
In this video, you'll learn how to properly configure and wire up a CosmosClient using FastAPI's dependency injection system. Instead of creating new connections for every request, we'll implement a singleton pattern with connection pooling that scales efficiently and integrates seamlessly with Azure Functions.
What You'll Learn:
• Connection pooling fundamentals and why every CosmosClient creates its own pool
• The performance difference between one connection pool versus hundreds
• Singleton CosmosClient pattern using global variables and lazy initialization
• Clean FastAPI dependency injection setup for database connections
• Azure Functions integration patterns that work in production
