Annotation Interface ScheduledTrigger

@Retention(SOURCE) @Target(METHOD) public @interface ScheduledTrigger
Declares that the annotated function should be executed on a schedule.

This annotation can be used in combination with Function to define time-based triggers using cron expressions. It enables the generation of scheduled tasks for serverless platforms that support them (e.g. AWS EventBridge, GCP Cloud Scheduler).

Example


 @Function(name = "dailyTask")
 @ScheduledTrigger(cron = "0 0 * * *", timezone = "Europe/Berlin")
 public Void runDailyTask() {
     // perform daily task
     return null;
 }
