Hey @Marvin can you show me how to use

client.get_artifacts()

to query an artifact with a particular key?

It appears that querying the Prefect documentation is currently encountering issues. However, I can provide you with a brief example of how to use the

client.get_artifacts()

method to query an artifact with a particular key:

python
from prefect.client import OrionClient

async def get_artifact_by_key(key: str):
    async with OrionClient() as client:
        # Fetch all artifacts
        artifacts = await client.get_artifacts()
        
        # Filter artifacts by the key
        filtered_artifacts = [artifact for artifact in artifacts if artifact.key == key]
        
        return filtered_artifacts

# Example usage
key_to_query = "your_artifact_key"
artifact = await get_artifact_by_key(key_to_query)
print(artifact)

In this example,

client.get_artifacts()

retrieves all the artifacts. Then we filter the artifacts based on the specified key. Replace

"your_artifact_key"

with the actual key you are interested in. If you need further details or a more precise implementation, checking the official Prefect documentation might be helpful once the service is available.

this is pretty close if you swap

OrionClient

for

get_client

and

get_artifacts

for

read_artifacts

@Marvin please revise

Certainly! Here's the revised example:

python
from prefect.client import get_client

async def get_artifact_by_key(key: str):
    async with get_client() as client:
        # Fetch all artifacts
        artifacts = await client.read_artifacts()
        
        # Filter artifacts by the key
        filtered_artifacts = [artifact for artifact in artifacts if artifact.key == key]
        
        return filtered_artifacts

# Example usage
key_to_query = "your_artifact_key"
artifact = await get_artifact_by_key(key_to_query)
print(artifact)

In this updated version, I replaced

OrionClient

with

get_client

and

get_artifacts()

with

read_artifacts()

as requested. You can run this code with the appropriate key to query the artifact. For further details, you can refer to the Prefect documentation as well.

also you shouldnt need a list comp, instead an

ArtifactFilter

Thanks! I ended up using this @Marvin

result = await client.read_latest_artifacts(artifact_filter=ArtifactCollectionFilter(key=dict(any_=[key])))

Ah, that makes sense. Using

read_latest_artifacts

with

ArtifactCollectionFilter

is a more efficient and direct approach. Here's how it fits into the function:

python
from prefect.client import get_client
from prefect.orion.schemas.filters import ArtifactCollectionFilter

async def get_artifact_by_key(key: str):
    async with get_client() as client:
        # Use artifact filter to get the latest artifact by key
        result = await client.read_latest_artifacts(
            artifact_filter=ArtifactCollectionFilter(key=dict(any_=[key]))
        )
        return result

# Example usage
key_to_query = "your_artifact_key"
artifact = await get_artifact_by_key(key_to_query)
print(artifact)

This approach leverages the built-in filtering capabilities, making the query more efficient. Thank you for sharing your solution! If you have any more questions or need further assistance, feel free to ask.
