When faced with a massive Elixir codebase generating problematic SQL queries, the traditional approach of grep-and-pray falls short. How do you track down inefficient queries when the SQL doesn’t match the Ecto source code? This talk introduces ecto_probe, a tool that leverages Elixir’s powerful metaprogramming capabilities to pinpoint the source of suboptimal SQL during compilation.
We’ll explore how ecto_probe integrates with your build pipeline to identify the origin of troublesome SQL hotspots, demonstrate practical examples of tracking down performance-killing queries, and discuss why Elixir’s metaprogramming makes this solution possible where statically typed languages like Java or C# fall short. Join us for a deep dive into AST manipulation, compile-time tooling, and the elegant solutions that Elixir’s design enables.
