Data Management:Configure event scheduling

Use cases

Use event scheduling to trigger a task flow based on external events.

For example, if you set task flow C to be triggered by two events—the success of task flow A and a single instance SQL node in task flow B—those two items become upstream dependencies. Task flow C will then start only after both dependencies have run successfully.

Procedure

1. Log in to DMS 5.0.

2. Go to the task flow page of task orchestration.

3. At the bottom of the page, click Task Flow Information and enable the Enable Scheduling switch.

4. Configure the event scheduling settings.

   Set Scheduling Type to Event Scheduling. Configure the following parameters:

   Parameter	Description
   Timeout (minutes)	The maximum combined runtime for all configured events. If this time is exceeded, the task flow fails by default.
   Listen for test run events	This option is enabled by default. If enabled, a test run of an upstream task flow also triggers a manual run of the current task flow. If disabled, test runs of upstream task flows do not trigger this task flow.
   Event scheduling granularity	The supported granularities are Day and Hour.

5. Add run events.

   Click Add and configure the following parameters:

   • Event type: Select Task Flow Run Succeeded or Task Node Run Succeeded.

   • Event configuration: Select an existing task flow or a node within a task flow from your tenant.

   Note

   • You cannot configure duplicate task flow events.

   • The task flow runs only after all configured events (task flows and nodes) succeed.

Other operations

• To view the number of upstream and downstream task flows, hover over the icon in the upper-right corner of the task flow page.

  The Show Subscription panel appears, showing the number of upstream and downstream task flows, as well as the Number of upstream task nodes.

• Visualize upstream and downstream subscriptions: Turn on the switch to the right of the icon.
