Globus Timers

Globus Timers provides a simple way to schedule asynchronous tasks. A timer can be used to schedule specific operations to occur at a particular time or to repeat at regular intervals. The Globus Timers service currently supports scheduling of flow runs and transfer tasks.

A timer is a definition of an operation to be performed and a schedule for when to perform it. Each time a timer's schedule condition is reached, a timer run is created. A timer run records the result of an operation, tracking its progress through completion.

Getting Started

The best way to get started is to try creating a timer. See the Scheduling a Transfer or Scheduling a Flow Run tutorials for a step-by-step guide to creating your first timer.

Understanding Timer Schedules

For more information on timer behaviors and scheduling options, the Timer Schedules document provides an overview of the options available when creating a timer, information about how timers behave in different situations, as well as instructions for pausing and resuming your timers.

Limits

The Globus Timers service has the following usage limits:

A user’s timers cumulatively cannot run more often than once per minute.
Only the last 90 days of activity are retained for a timer.

CLI, SDK, and APIs

Globus Timers is supported in the Globus CLI and the Globus Python SDK.
