Is there any way to define which task executes first and second task has to be executed only after first task is executed Both of these tasks loads same data from a loader function

Hi @Kayvan Shah - would you mind sharing some minimal code for what you've tried?

upstream_tasks

should work for what you're thinking

Sample code for `upstream_tasks`:

import prefect 
from prefect import Flow, task

@task
def mytask():
    return 1

with Flow('test-flow') as flow:
    a = mytask()
    b = mytask(upstream_tasks=[a])

flow.run()

Untitled

You can try something like this:

with Flow("Harvest_Demo") as flow:
    path_config = load_path_config()
    x = harvest_metadata(path_config)
    harvest_master_data(path_config, upstream_tasks=[x])

Thanks That worked

The x will hold the value and state of the

harvest_metadata

task and the

harvest_master_data

task will grab the state from x even if there is no return value in this case.
