Utilizing Reactor for Improved Nerves Device Startup

In this presentation, James Harton discusses his innovative approach to starting up Nerves devices by leveraging Reactor, a graph-powered saga runner designed to manage operations with transaction-like semantics across system boundaries. He outlines how Reactor's graph-driven asynchrony can drastically shorten the startup times for Nerves applications. The talk includes an overview of Reactor's typical usage in Elixir applications, showcasing how to execute file operations and replacing standard startup processes for Nerves applications with Reactor.
