🗄️ Low-Level Caching with Rails.cache.fetch

Cache expensive computations or slow external calls. Use fetch with an expiration to store the result in your cache store and avoid repeated work.

# Cache dashboard stats for 10 minutes
dashboard_stats = Rails.cache.fetch("dashboard_stats", expires_in: 10.minutes) do
  StatsService.calculate_all
end
