To schedule a job, you must create the following configuration objects:
Define a schedule - For each supported asset type, you can define a schedule. A schedule specifies one or more recurring times (triggers) when scheduled jobs are executed. For example, in a single schedule, you can specify daily trigger times for incremental updates and monthly execution times for rollups.
Tip: The scheduler supports a modified form of cron job syntax. For more information, see cron Schedule Syntax Reference.
Define one or more scheduled destinations - When you specify a scheduled destination, the upstream sets of transformation steps are executed whenever one of the schedule's execution times occurs. Scheduled destinations are specified like regular destinations.
NOTE: When a schedule is triggered, all transformation jobs upstream of the scheduled destination are executed. Manual destinations are not generated. You cannot create schedules for individual outputs.
- One schedule cannot be applied to multiple assets.
- You cannot create separate schedules for individual assets within a flow or workflow.
- Only an asset owner can create or modify the asset's schedule.
NOTE: Since scheduled destinations are re-populated with each scheduled execution, you must determine how you wish to manage the data that is published to each location. Data management should be done outside of the Designer Cloud Powered by Trifacta platform.
- Import: Before each scheduled execution, you should refresh the source of the imported dataset with new data outside of the Designer Cloud Powered by Trifacta platform.
- Execution: Please verify that the publishing settings for your scheduled destination are consistent with how you are using the results. For example, if the scheduled destination creates a new file with the same name for each execution (replace), you must move the generated file out of the output location before the next scheduled execution.
- Output: You must collect the generated results. While you can export the job's results through the Job History page, you may find it easier to use an external scheduler to gather the results and forward to the downstream consumer of them.
Flows for scheduling
Tip: When a schedule is executed, all outputs in a flow are generated, even if they are unused. For better performance on larger flows, you can create a separate flow that contains only the references back to the objects in the source flow that you wish to have scheduled. As an additional benefit, this separation keeps development and scheduled execution in separate flows.
Schedule a Job
Schedules and scheduled destinations are defined through the Schedules page. See Schedules Page.
You can monitor a scheduled job like any other job in the application. See Job History Page.
