In my view, the presence of YAML templating is a red flag in any codebase or system. YAML got its popularity with the advent of Ruby on Rails, largely due to the simplicity of the database.yml file as an aid in database connection string abstraction that felt extremely clean to Java programmers who were used to complicated XML files full of DSN names and connection string peculiarities. The evolution of the database.yml file into something arguably as complex as the thing it was intended to replace is described in the article below: https://dev.to/andreimaxim/the-rails-databaseyml-file-4dm9 https://dev.to/andreimaxim/the-rails-databaseyml-file-4dm9
