Do You Really Need Processes? by Brian Underwood | Code BEAM Europe 2023

✨This talk was recorded at Code BEAM Europe 2023. If you're curious about our upcoming event, check codebeameurope... ✨
Abstract:
You probably know that the power of the BEAM comes from processes which operate concurrently and supervisors which, in many cases, allow service to continue. Maybe you’ve thought that your application needs to use more GenServers and Supervisors to become the best that it can be. But then again, maybe everything is fine.
In this talk, Brian will present a demo of a ride-sharing application which he created to understand what is possible with a standard Phoenix + PostgreSQL application. He will explore what performance and resiliency gains can (or can’t) be achieved by designing various process and supervision architectures using an external database, process state, ETS tables, and combinations therein.
