Overview of Scheduling
As needed, you can schedule the execution of jobs on a recurring basis. For example, if your source data for the job is updated outside of the application every week, you can define a schedule to the job associated with the related imported dataset after the data has been refreshed. When the scheduled job successfully executes, you can collect the transformed output in the specified output location, where it is available in the published form that you have specified.
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.
ヒント
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.
注記
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.
Limitations
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.
Data Management
注記
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 Alteryx Analytics Cloud.
Import: Before each scheduled execution, you should refresh the source of the imported dataset with new data outside of the Alteryx Analytics Cloud.
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.
Schedule a Job
Schedules and scheduled destinations are defined through the Schedules page. See Schedules Page.
Job Execution
Tracking
You can monitor a scheduled job like any other job in the application. See Job History Page.
