Explore how to write Elixir code as if all Ecto data is already loaded in this 39-minute conference talk from Code BEAM Europe 2024. Discover the Dx library, which enables pattern matching to match associations, using Enum functions to navigate associated data, and accessing fields in associations without additional data loading considerations. Learn how Dx (data-driven Elixir) translates Elixir code to run optimized for the database, similar to how Nx translates code for GPU optimization. Understand how Dx converts your code either to Ecto queries or to versions with automatic data loading, optimized through batching and concurrency. See how this approach creates clear, maintainable Elixir code structured in standard modules and functions without requiring manual data loading implementation, while maintaining efficiency compared to traditional Ecto queries and preloading methods.
