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 Presenter Gwyneth Peña-Siguenza Links: • Code Repository: https://msft.it/63322ShMAk • Azure Functions Best Practices: https://msft.it/63324ShMAw • Azure Cosmos DB Python Best Practices: https://msft.it/63325ShMAb • FastAPI Dependency Injection: https://msft.it/63326ShMAj • Subscribe to Azure Cosmos DB on YouTube – https://msft.it/63327ShMAd • Follow Azure Cosmos DB on X – https://msft.it/63329ShMA5 • Follow Azure Cosmos DB on LinkedIn – https://msft.it/63321ShMA9 #Python #AzureCosmosDB #Azure #NoSQL #DatabaseTutorial #PythonSDK https://msft.it/63323ShMAc
