ages and services previously written in java or Ruby which encountered issues with concurrency and scalability, found converting to Elixir very beneficial. In my latest article, I have examined examples of companies like Discord, Pinterest, Bleacher Report and Moz improving their services' performance with Elixir.
During the recent addition of distribution to Cachex, I realised that testing distributed behaviour is quite annoying. Although there's a tonne of useful inside the OTP standard library, it's not particularly obvious if you don't know what you're looking for. Most projects (such as Phoenix) roll their distributed tests around these standard tools directly, which means that there's little out there in terms of utilities for the general masses.
In a recent project, I had to implement idempotent API endpoints in a Phoenix application. And as a part of this, I had to store the MD5 hash of each request body along with its idempotency key and other request data. And the latest Plug makes this easier thanks to this PR.
