r""" |
|
A example workflow for task dependent. |
|
|
|
This example will create two workflows named `task_dependent` and `task_dependent_external`. |
|
`task_dependent` is true workflow define and run task dependent, while `task_dependent_external` |
|
define outside workflow and task from dependent. |
|
|
|
After this script submit, we would get workflow as below: |
|
|
|
task_dependent_external: |
|
|
|
task_1 |
|
task_2 |
|
task_3 |
|
|
|
task_dependent: |
|
|
|
task_dependent(this task dependent on task_dependent_external.task_1 and task_dependent_external.task_2). |
