Is there a way to return persisted results via the PREFECT API? I mean the actual results, not meta data 🙂

You are able to view the results via the api if you stream the results to logs and then query the logs via the Rest Api

OK, thanks for the quick answer :)

hi @Robin - results can be accessed without sending them to the logs. If the persisted result exists, you can retrieve the result attached to the state of a flow run like

Copy code

In [14]: !prefect flow-run ls | ag  b99be877
│ b99be877-74c0-4522-ba75-74d102a479a9 │ Execute LLM Call │ Calling langchain.llms.openai │ COMPLETED │ 6 days a… │

In [15]: from uuid import UUID

In [16]: from prefect import get_client

In [17]: async with get_client() as client:
    ...:     flow_run = await client.read_flow_run(flow_run_id=UUID("b99be877-74c0-4522-ba75-74d102a479a9"))
    ...:     print(flow_run.state.result())
    ...:
None

Oh, that is much better 👌

What is the most elegant way to stream task progress? e.g. I guess "printing progress to the logs and then querying the logs via REST API" is one option, but maybe there is as well a better option for that?
