Leveraging Ecto Multis and Oban for Better Transaction Handling in Elixir

In this talk from ElixirConf US 2024, Miki Rezentes addresses the challenge of updating multiple entities at once in Elixir applications. He highlights the necessity of managing side effects, such as event emissions and logging, which can lead to inconsistent behaviors if handled poorly. The talk emphasizes that traditional methods can increase cognitive load and complicate responsibilities. By employing Ecto Multis and Oban, developers can manage transactions more effectively. Furthermore, the implementation of transaction callbacks is presented as a way to maintain consistency and simplify code, showcasing practical examples of lower cognitive load and better code management.
