Schedule triggers in Azure Data Factory allow pipelines to be executed according to a timed schedule. A schedule trigger specifies a start date, recurrence, and end date that determines how often the associated pipeline will run. Triggers can be configured to very specific schedules like every month or every Sunday at 9:00PM. This offers more flexibility than simple recurring schedules like every hour or day. Multiple triggers can be used to kick off a single pipeline, and a single trigger can trigger multiple pipelines.
