class aws_cdk.aws_scheduler_alpha.ScheduleExpression

Bases: object

(experimental) ScheduleExpression for EventBridge Schedule.

You can choose from three schedule types when configuring your schedule: rate-based, cron-based, and one-time schedules. Both rate-based and cron-based schedules are recurring schedules.

ScheduleExpression

classmethod expression(expression, time_zone=None)

(experimental) Construct a schedule from a literal schedule expression.

Parameters:

  • expression (str) – The expression to use. Must be in a format that EventBridge will recognize

  • time_zone (Optional[TimeZone]) – The time zone to use for interpreting the expression. Default: - UTC

ScheduleExpression

classmethod rate(duration)

(experimental) Construct a recurring schedule from an interval and a time unit.

Rates may be defined with any unit of time, but when converted into minutes, the duration must be a positive whole number of minutes.

Parameters:
