Description
Configuration
@Configuration
public class DbSchedulerConfiguration {
@Bean
RecurringTask<Void> staticRecurringTask() {
CronSchedule schedule = cron("*/1 * * * * *"); // High frequency for testing purposes. Normally once a day.
return Tasks.recurring("Trigger job", schedule)
.onFailure(new FailureHandler.MaxRetriesFailureHandler<>(5,
new FailureHandler.ExponentialBackoffFailureHandler<>(Duration.ofSeconds(3), 1),
new FailureHandler.OnFailureReschedule<Void>(schedule)::onFailure))
.execute((instance, ctx) -> {
System.out.println("Running staticRecurringTask");
throw new RuntimeException("Error");
});
}
}
Expected Behavior
"Trigger job" is rescheduled again after the 5 retry attempts have failed.
Current Behavior
"Trigger job" has been removed from the DB by calling executionOperations.stop(); See: https://github.com/kagkarlsson/db-scheduler/blob/master/db-scheduler/src/main/java/com/github/kagkarlsson/scheduler/task/FailureHandler.java#L96
Therefore the attempt to reschedule the task will fail.
Proposed solution
If a maxRetriesExceededHandler is defined, let it decide whether the task is stopped/removed.
Workaround
Define your own MaxRetriesFailureHandler which does not stop/remove the task by implementing the provided interface.
Context
