Cron Scheduling

Comparable to: node-cron, APScheduler, crontab

Key Concepts

Use the concepts below when they fit the task. Not every scheduled job needs all of them.

• Cron expressions use a 7-field format: second minute hour day month weekday year
• CronModule evaluates expressions and fires triggers on schedule
• Handlers should be fast — enqueue heavy work to a queue instead of blocking the cron handler
• Each cron trigger binds one expression to one function
• Overlapping schedules are fine; each trigger fires independently

Architecture

CronModule timer tick
  → registerTrigger type:'cron' expression match
    → registerFunction handler
