Schema-Less Upserts with Ecto in Elixir

Working with dynamic data or rapid database writes in Elixir often requires bypassing formal schemas for maximum performance and flexibility. This text-based course guides you through the foundational concepts of managing database conflicts directly using Ecto. You will learn how to safely insert and update records using unique constraints and raw database operations. By completing this course, you will be able to confidently handle complex database write patterns and resolve conflicts programmatically without the overhead of maintaining strict Ecto schemas. What you'll learn: - Understand the core mechanics of schema-less database interactions in Ecto - Configure unique database indexes to safely detect record conflicts - Apply on_conflict strategies to determine how data updates are handled - Master the use of Ecto.Repo.insert_all for efficient batch operations - Implement modern Elixir database patterns including dynamic query building Starting with fundamental database concepts and configuration, this course walks you through real-world scenarios, showing you how to handle conflicts, update existing records on the fly, and optimize your application's data layer. You will read through clear explanations, analyze practical code snippets, and study structured database workflows. This course is designed for beginner to intermediate Elixir developers who are familiar with basic database concepts and want to write more flexible, high-performance data persistence logic.
