Is there a way to use one asset as a dependency of another asset without having to define an AssetKey

Yes, there is a way to use one asset as a dependency of another asset without having to define an

AssetKey

. You can specify asset dependencies directly by referencing the asset functions or the assets themselves. Here's an example from the documentation that demonstrates how to define dependencies between assets:

python from dagster import asset  @asset def upstream_asset():     ...  @asset def downstream_asset(upstream_asset):     ...

In this example,

downstream_asset

depends on

upstream_asset

, and the dependency is declared by simply passing

upstream_asset

as a parameter to

downstream_asset

. This approach allows you to define dependencies without explicitly using

AssetKey

.
