Original: The Symfony Scheduler Component: Cron in Your App, Not Your Crontab

Short summary

The Symfony Scheduler component moves recurring task definitions from system crontabs into versioned PHP code, making them reviewable, testable, and deployable with your application. It supports both human intervals and standard cron expressions, with a hashed cron feature that spreads execution times across your fleet. Tasks integrate seamlessly with Symfony Messenger's retry and failure strategies.

  • Scheduler shifts tasks from crontab to versioned PHP code with full code review and testing
  • Hashed cron expressions prevent load spikes by spreading execution across your fleet
  • Integrates with Symfony Messenger for consistent retry and error handling
