Ecto Performance Tuning for Elixir Applications

When Elixir applications slow down, the bottleneck is almost always in how they talk to the database. Understanding how to write efficient Ecto queries and structure your data access is critical to building responsive, scalable software. This text-only course guides you from database-access basics to advanced query optimization strategies. You will start with core database concepts and Ecto fundamentals before diving into real-world performance tuning. Through clear, written explanations and structured code analysis, you will learn how to identify bottlenecks and write highly efficient database interactions. What you'll learn: - Understand the fundamentals of Ecto repository patterns and query generation - Detect and eliminate N+1 query problems using preload and join strategies - Analyze database execution plans directly from your Elixir code - Configure efficient connection pooling and handle concurrent database access safely - Implement query caching and modern data retrieval patterns to minimize database load - Apply index design principles to optimize database search performance This course begins with essential database definitions and Ecto architectures, then transitions into practical performance profiling and optimization techniques. It is designed for beginner to intermediate Elixir developers who want to write faster, database-efficient applications without any prior tuning experience.
