Most applications have background jobs that require managing. While a basic queue implementation is simple to write, it could riddle your system with tight coupling, and straddle the developers with multiple nearly-duplicate implementations. In this talk, I will explain our design constraints for such a task queue system, and present an implementation, taking into account Elixir’s strengths in concurrency, state management, and node clustering. I will also examine the performance characteristics of such an implementation. More details on the website: http://www.elixirconf.eu/elixirconfeu2018/evadne-wu
