Single Pipeline Approach

Workflow - Single Pipeline Approach

1. Single Pipeline Approach is the procedural scripting.
2. Every workflow has only one (1) task of main function which is registered and started in the celery
3. main function
   1. Registered as a task
   2. main(self, task_name="main", *args, **kwargs) -> (status:str, err_msgs:list[str], data:object)
   3. the function intended to define the sequence of the functions for execution. 
   4. has the access to credentials
   5. receives the payload
   6. must verify that the payload provided is correct: right types and values, all other functions assume that payload is correct
4. other functions
   1. assume the payload is correct
   2. other arguments are not guaranteed to be valid 
   3. other(self, task_name, *args, **kwargs) -> (status:str, err_msgs:list[str], data:object)
