Ecto Multi: Integrating External Operations in Elixir Transactions

When building Elixir applications, you often need to perform external tasks—like sending welcome emails or calling third-party APIs—only when a database transaction successfully commits. Managing these side effects safely without leaving your system in an inconsistent state is a common challenge. This course teaches you how to orchestrate complex database operations alongside arbitrary Elixir code using Ecto Multi. You will learn to design predictable, maintainable, and rollback-safe transactional workflows. What you'll learn: - Understand the core concepts of database transactions and the role of Ecto Multi. - Implement Ecto.Multi.run to execute custom Elixir functions within a transaction block. - Handle failures and rollbacks gracefully across both database and non-database operations. - Structure clean error handling using pattern matching and Elixir's control flow. - Apply modern patterns for decoupled event publishing and background jobs after successful commits. Starting with foundational transaction concepts, you will progress to writing custom multi-step operations and managing external side effects safely. This course is designed for developers familiar with basic Elixir and Ecto who want to master transactional workflow design. Start reading today to build more robust and reliable Elixir applications.
