If a node is scheduled by minute, the node is automatically run once every N minutes
within a specific period every day.
Limits
The minimum time interval for a node that is scheduled by minute is 5 minutes.
Configuration example
- Configuration method
On the DataStudio page, create a node and go to the configuration tab of the node. Click the Properties tab in the right-side navigation pane. In the General section of the Properties tab, configure the scheduling period for the node.
- ScenarioThe following figure shows how to configure a node that is scheduled to run every 30 minutes from
00:00
to23:59
every day.Note The cron expression is automatically generated based on the scheduling time that you select and cannot be changed. - Scheduling details
The following figure shows the scheduling time of instances generated for a node scheduled to run every 30 minutes and the replacement results of the scheduling parameters configured for the node.
Scenario: A node scheduled by minute depends on a node that has a different scheduling frequency
DataWorks allows you to configure scheduling dependencies between the nodes whose scheduling frequencies are different. Before you configure scheduling dependencies, you can learn the principles of configuring scheduling dependencies. After you have a command of the principles, you can configure the scheduling dependencies of nodes based on your business requirements. For information about scheduling dependencies in complex dependency scenarios and the related illustrations, see Principles and samples of scheduling configurations in complex dependency scenarios.
- If a node scheduled by minute depends on a node scheduled by day, the instances generated for the node scheduled by minute on the current day depend on the instance generated for the node scheduled by day on the current day. In this case, the instances generated for the node scheduled by minute on the current day can start to run only after the instance generated for the node scheduled by day on the current day is successfully run.
- If a node scheduled by minute depends on a node scheduled by hour, the instances generated for the node scheduled by minute depend on the instances generated for the node scheduled by hour based on their scheduling time and the principle of scheduling time proximity.
