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.

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