Custom Indexing in Azure Cosmos DB for NoSQL

In NoSQL databases, inefficient indexing can quietly drain your budget and slow down your application. Mastering how to customize indexing policies in Azure Cosmos DB for NoSQL is the key to balancing fast query performance with low write costs. This text-only course guides you from the fundamental concepts of NoSQL indexing to implementing advanced custom policies. You will learn how to transition from default automatic indexing to precisely targeted indexing strategies that optimize your Request Units (RUs) and boost overall database efficiency. What you'll learn: - Understand core indexing terminology, default indexing behaviors, and how Azure Cosmos DB stores index data - Configure custom single-path and wildcard indexing policies to match your specific query patterns - Create composite indexes to optimize complex queries with multiple properties and sorting requirements - Analyze query performance and Request Unit consumption to identify indexing bottlenecks - Manage indexing progress and safely apply policy updates to active production containers You will start with foundational definitions and key indexing mechanics before moving into step-by-step written guides on editing JSON index policies. Through practical scenarios and structured written examples, you will learn to fine-tune your database for maximum cost-efficiency. This course is designed for beginner cloud developers, database administrators, and data engineers who are new to Azure Cosmos DB and want to learn indexing fundamentals. No prior indexing experience is required. Start reading today to take control of your database performance and optimize your cloud spend.
