Upon first glance, it seems very straightforward to run Elixir on Ecto tests in parallel. Ecto has a guide on this here. However, enabling async: true only works if the concurrent processes that are running Ecto queries are properly associated with your primary test process.
This is the second part of a series of posts that I will present on how your application can use Event Sourcing and CQRS for specific domains with an open-source library that I am developing called Incident. If you haven't read the first part I highly recommend it as it will describe the library goals, some important Event Sourcing and CQRS concepts, library configuration, and basic usage.
I finished setting up the first schema with everything needed to CRUD (create / edit / update / delete) a record in the destinations table. The views and forms are functional, but they definitely need some love, particularly the index view.
It was the first day of my first Erlang-based system in production. I’ve invested some sensible amount of time to test and stabilize it. I’s were dotted, t’s were crossed and I felt confident that it would work reasonably well. The system broke in production within the first few hours of its life.
Anyone who's moderately familiar with Elixir has probably at least heard of GenServer. (If you haven't, that's ok too!) Strictly speaking, it's one of those things you can get away with avoiding for a while, and still be reasonably productive while using something like the Phoenix framework.
