Seed Scheduler documentation

The Seed Scheduler is one of the microservices in the Seed Stack.

The Scheduler has the following key responsibilities:

  • Allow other services to create scheduled callbacks via the API.
  • At the scheduled time, call the configured URLs with the configured payload.

Getting started

The following resources are provided to help you get started running or developing the Seed Scheduler:

How the task scheduling works

The Seed Scheduler uses Celery and the django-celery integration package to handle the scheduling of the periodic tasks.

The schedules are kept in tables in the PostgreSQL database that a Celery beat worker processes and then hands off actual task execution to another Celery worker process.

When a new Schedule object is created via the Seed Scheduler API, a corresponding django-celery PeriodicTask object is created for that schedule.
