Artifact Stores
zenml.artifact_stores
special
ZenML's artifact store stores artifacts in a file system.
In ZenML, the inputs and outputs which go through any step is treated as an
artifact and as its name suggests, an ArtifactStore
is a place where these
artifacts get stored.
Out of the box, ZenML comes with the BaseArtifactStore
and
LocalArtifactStore
implementations. While the BaseArtifactStore
establishes
an interface for people who want to extend it to their needs, the
LocalArtifactStore
is a simple implementation for a local setup.
Moreover, additional artifact stores can be found in specific integrations
modules, such as the GCPArtifactStore
in the gcp
integration and the
AzureArtifactStore
in the azure
integration.
base_artifact_store
The BaseArtifactStore
offers an interface for extending the ZenML artifact store.
