Hello, I am trying to schedule metadata ingestion flows for Amundsen using Prefect. The Amundsen code that I am trying to schedule has run() function. So on trying to run the code as part of task is failing. Do you have any suggestions to schedule such type of flows? We are currently using Perfect1.0 Thank you, Divya

Hi @Kevin Kho, Thanks for getting back. Please find the code below:
Copy code
@task()
def postgres_task():
    loading_job = run_postgres_job()
    loading_job.launch()

@task()
def es_launch():
    job_es_table = create_es_publisher_sample_job(
        elasticsearch_index_alias='table_search_index',
        elasticsearch_doc_type_key='table',
        model_name='databuilder.models.table_elasticsearch_document.TableESDocument')
    job_es_table.launch()

def perfect_flow():
    with Flow(name = 'sample_postgres_loader') as flow:
        postgres_task()
        es_launch()
    return flow

if __name__ == "__main__":
    flow = perfect_flow()
    flow.run()
    flow.register(project_name="default")
``````
Also the Amundsen code is from the git repo attached. https://github.com/amundsen-io/amundsen

to schedule this flow, you would need to attach a schedule to the flow and register the flow but you may also consider doing this in Prefect 2.0 instead if you're getting started with Prefect now - docs: https://orion-docs.prefect.io/getting-started/overview/
