Type Members

1. case class CronContext(instant: Instant)(retryNum: Int) extends SchedulingContext with Product with Serializable

   

   A CronContext is passed to executions initiated by the CronScheduler.

2. type CronExecution = Execution[CronScheduling]

   

3. type CronJob = Job[CronScheduling]

   

4. class CronProject extends AnyRef

   

   A cuttle project is a workflow to execute with the appropriate scheduler.

   A cuttle project is a workflow to execute with the appropriate scheduler. See the CronProject companion object to create projects.

5. case class CronScheduler(logger: Logger) extends Scheduler[CronScheduling] with Product with Serializable

   

   A CronScheduler executes the set of Jobs at the time instants defined by Cron expressions.

   A CronScheduler executes the set of Jobs at the time instants defined by Cron expressions. Each Job has it's own expression and executed separately from others.

   The Scheduler ensures that at least one Execution is created and successfully run for a given time instant. It also handles the retry policy.

   We follow the semantic of Cron on Unix systems and we don't manage misfires (meaning that if the scheduler missed some events because it was offline, or because a previous job execution was still running, we won't replay them).

   Job is considered as finished when we can't produce the next computing instant from Cron expression.

6. case class CronScheduling(cronExpression: String, maxRetry: Int) extends Scheduling with Product with Serializable

   

   Configure a job as a CronScheduling job.

   Configure a job as a CronScheduling job.

   cronExpression

   Cron expression to be parsed by https://github.com/alonsodomin/cron4s. See the link above for more details.

   maxRetry

   The maximum number of retries authorized.

7. case class CronWorkload(jobs: Set[CronJob]) extends Workload[CronScheduling] with Product with Serializable

   

   Class regrouping jobs for scheduler.

   Class regrouping jobs for scheduler. It doesn't imply any order.

   jobs

   Jobs to schedule.
