The Prefect documentation does not explicitly mention a direct feature in the UI to download metadata of completed flows, subflows, and tasks in JSON or YAML format. However, you can programmatically retrieve this information using the Prefect API.
To gather such metadata, you would typically use the Prefect client to query for flow run details, subflow runs, and task runs. This can be done using Prefect's Python API, where you can access the metadata and then format it as JSON or YAML.
Here's a general approach you might consider:
1.
Use Prefect Client: Connect to the Prefect server using the Prefect client.
2.
Query Flow Runs: Retrieve the metadata for the flow run, subflows, and task runs.
3.
Format the Data: Convert the retrieved data into JSON or YAML format using Python libraries like
json
or
pyyaml
.
For more detailed examples and API usage, you might want to explore Prefect's API documentation or check their GitHub repository for code snippets related to flow and task metadata retrieval.
