If a node is scheduled by hour, the node is automatically run once every N hours within a specific period every day. For example, a node is run once every hour from 00:00 to 03:00 every day.

Limits

You can schedule a node to run by hour only on the hour during the specified period. For example, you cannot schedule a node to run once every hour during the period from 00:05 to 23:59.

Precautions

  • The period is a left-closed, right-closed interval. For example, if a node is scheduled to run once every hour during the period from 00:00 to 03:00, the scheduling system generates four instances for the node every day, and the four instances are run at 00:00, 01:00, 02:00, and 03:00 in sequence.
  • You can schedule a node to run at specified intervals within a specific period every day. You can also schedule the node to run at specified points in time on the hour every day.
  • The time at which a node is actually run may be different from the configured time due to reasons such as insufficient resources.

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.
