Goodbye Scattered Cron Jobs: Heartbeat's Centralized Task Scheduler
2025-08-01
Heartbeat previously used multiple Cron Jobs to manage scheduled tasks, resulting in high maintenance costs and frequent errors. This article describes how they built a centralized, database-driven task scheduler using a single `ScheduledTasks` database table and a single Cron Job to manage all scheduled tasks. Leveraging AWS SQS for asynchronous processing, the system ensures reliable task execution, retry mechanisms, and robust monitoring. This approach addresses issues like task management chaos, difficult error handling, and simplifies the addition of new scheduled tasks.
