Dependent

Overview

Dependent nodes are dependency check nodes. For example, process A depends on the successful execution of process B from yesterday, and the dependent node will check whether process B run successful yesterday.

Create Task

  • Clickย Project Management -> Project Name -> Workflow Definition, and click theย Create Workflowย button to enter the DAG editing page.
  • Drag from the toolbar task node to canvas.

Task Parameter

Parameter Description
Node name Unique name of node in workflow definition.
Run flag Identifies whether this node schedules normally.
Description Describe the function of the node.
Task priority When the number of worker threads is insufficient, execute in the order of priority from high to low, and tasks with the same priority will execute in a first-in first-out order.
Worker group Assign tasks to the machines of the worker group to execute. If Default is selected, randomly select a worker machine for execution.
Task group name The group in Resources, if not configured, it will not be used.
Environment Name Configure the environment name in which run the script.
Number of failed retries The number of times the task failed to resubmit.
Failed retry interval The time interval (unit minute) for resubmitting the task after a failed task.
Delayed execution time The time (unit minute) that a task delays in execution.
Pre task Selecting a predecessor task for the current task, will set the selected predecessor task as upstream of the current task.

Task Examples

The Dependent node provides a logical judgment function, which can detect the execution of the dependent node according to the logic.

For example, process A is a weekly task, processes B and C are daily tasks, and task A requires tasks B and C to be successfully executed every day of the last week.

dependent_task01

And another example is that process A is a weekly report task, processes B and C are daily tasks, and task A requires tasks B or C to be successfully executed every day of the last week:

dependent_task02

If the weekly report A also needs to be executed successfully last Tuesday:
