What should I know about scheduled trigger behavior and limits?

Behavior

Scheduled triggers automatically invoke a workflow at configured time intervals. When you create a scheduled trigger, you define the schedule, for example, using a cron expression, and the workflow runs according to that schedule without requiring an external event. Scheduled triggers execute solely based on a defined schedule and do not depend on event-based conditions.

Scheduled triggers do not support test mode because they are time-based rather than event-driven and cannot be manually executed. To validate a scheduled trigger, you must enable it and allow it to run according to its configured schedule.

Limits

Scheduled triggers are subject to the following limits:

• A scheduled trigger can be invoked at most two times per hour.
• Workflow invocation limits are shared between scheduled triggers and event triggers.

Workflow executions initiated by scheduled triggers are included in the same limits as those workflows initiated by event-based triggers. The shared workflow invocation limits are:

• event.orchestration.workflow.invocations.per.hour
• event.orchestration.workflow.invocations.per.minute

If the combined number of workflow invocations from both scheduled and event triggers exceeds these limits, additional invocations are throttled according to the configured rate limits.
