Safe Ecto Migrations: Running Outside Transactions in Elixir

Database migrations on large, active production tables can easily cause locking issues and unexpected downtime if handled incorrectly. This written course teaches you how to design and execute database migrations outside of standard transactions using Ecto. You will learn to safely perform heavy database updates and index changes on live production systems without interrupting your users.\n\nWhat you'll learn:\n- Understand the core mechanics of database locks and Ecto's default transaction behavior.\n- Configure migrations using the disable DDL transaction attribute safely.\n- Create database indexes concurrently to avoid blocking read and write operations.\n- Execute large-scale data migrations in controlled batches to minimize database load.\n- Apply lock timeouts and safety guards to prevent migration bottlenecks.\n\nThis course starts with foundational database concepts and migration safety principles before diving into practical, text-based code examples and migration patterns. It is designed for Elixir developers who already know the basics of Ecto and want to level up their production database management skills.\n\nBegin reading today to master safe, zero-downtime database migrations in your Elixir applications.
