Process Naming and Management in Elixir and Erlang

The article titled 'Naming your Daemons' by Tee Teoh, published on 2nd May 2024, discusses the concept of daemons in Unix systems and parallels within BEAM applications. It advocates for naming processes to organize and manage them better, to support fault tolerance, and to implement design patterns like Singleton or Coordinator. Elixir and Erlang allow process registration using atoms, but dynamic composite names typically use a two-step registration to avoid atom exhaustion. Alternatives, such as 'gproc' and Elixir's built-in 'Registry', are proposed for better dynamic process management. An 'Example' section demonstrates using 'gproc' for process registration in Elixir. The article concludes that alternative registries like 'gproc' allow for greater flexibility by avoiding atom-based registration, with 'Registry' being a more Elixir-native option.
