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).
