Function schedules let you run Cognite Functions automatically at defined intervals using cron expressions. Each schedule is linked to a specific function and can include input data that is passed to the function on each execution.

​
What function schedules do

A schedule defines when a function should run. You specify a cron expression (for example, every hour or every day at midnight) and optionally provide input data. CDF creates a function call according to the schedule, passing the configured input to the function.

​
Managing schedules

  • Create: Define a new schedule with a cron expression and optional input payload.
  • List: View all schedules for a function or across your project.
  • Delete: Remove a schedule to stop automatic executions.
  • Inspect: Retrieve schedule details including the cron expression and input configuration.
Schedules use standard cron syntax. Ensure your cron expression is valid for your desired execution frequency.

​
Sessions

A schedule fires asynchronous calls with the input in data and the cadence in a cron expression. Set either functionId or functionExternalId, not both. functionExternalId is deprecated. When you create a schedule with a nonce, you must use functionId. The nonce binds a session before each run, and CDF keeps that session for the life of the schedule.
Do not put secrets in the schedule data object. Store secrets on the function.

​
Use cases

Use schedules for periodic data syncs, recurring reports, cleanup tasks, or any workflow that should run on a fixed interval. Combine schedules with functions to automate data processing without manual invocation.
