02/21/2023, 1:33 PMHi asked similar question on another channel, but thought this channel might be better. I am playing around with Prefect 2 and I ran into 3 questions about running deployments:
1. is it possible to retrieve a flows result when ran with prefect.deployments.run_deployment?
2. when you persist data from a flow/task, is there a way to get the file name? or set up the location to be determined by a function so the file can otherwise be found?
3. Is it possible to manually read the data from a PersistedResult file?
questions 2 and 3 are admittedly related to each-other. Any help that can be provided on the above will be appreciated

(FlowRun.state.result()).get()Aaron Gonzalez

The results of the worker flows are persisted and gathered within the orchestrator flow by awaiting.(FlowRun.state.result()).get()

02/23/2023, 4:23 PMgood news, managed to answer question 3 myself.
If you are using LocalFileSystem the data can be read by using some navigation.
if you open the file, load the json, and convert the data to utf-8 bytes then the serialize objects ".loads()" method can be used to deserialize the data.
now I just need to figure out if you can name/organise the presisted data files in any way
