142: Orion for Distributed Tracing in Production
Thinking Elixir Podcast
00:00
Elixir
The Orion library is a dynamic profiler. It allows you to see how fast functions are running in production on the world cluster. The language was developed as an alternative to object-oriented programming (OOP) languages like C and Java. Elixir has been around for six or seven years, but it's only just become widely used by software developers.

Episode notes
Orion is an interesting library created by Thomas Depierre that makes it easy to run dynamic distributed tracing in your app on production! It includes a LiveView UI for visualizing the performance and running multiple traces simultaneously. We talk with Thomas to learn more about the history, the inspirations, how it works, why it's safe to run in production, how to get performance insights, and more!
