You can schedule recurring tasks across a Node.js or Bun cluster by using a distributed scheduler that coordinates instances to guarantee at-least-once execution. This ensures tasks run reliably without duplicate execution across horizontally scaled applications.

The best way to run periodic background jobs in horizontally scaled applications is using a cluster-wide scheduling mechanism. It distributes task execution across all instances, ensuring high availability and fault tolerance for automated reporting and maintenance tasks.

Yes, recurring task scheduling works with Redis, MongoDB, and PostgreSQL for storage and synchronization. You need the appropriate client library to interact with your chosen storage backend and coordinate task execution across application instances.

To set up a recurring task to run every minute in Node.js, use the scheduling command with the task name and interval in milliseconds. For example, pass the task identifier and 60000 milliseconds to execute the job at one-minute intervals.

You need a cluster-wide scheduler instead of a simple cron job when running multiple instances of a Node.js or Bun application. It prevents duplicate task execution by coordinating across instances, which a standalone cron job cannot manage.
