Hey all, is there a way to have wildcards in

AssetSelection

? For instance, I have a bunch of objects that have keys like

["grandparent", "parent", "child"]

and I want to select everything under

parent

You want this guide. https://docs.dagster.io/concepts/ops-jobs-graphs/job-execution

Hey Drew, appreciate the response. I don't think I see anything for my use case though. It seems like everything there is pinned on first providing the full key for a specific op, no wildcards

How about:

AssetSelection.keys(["grandparent"]) + AssetSelection.keys(["parent"]).downstream()

? The

.downstream()

method will pick up all assets that depend on that asset key and and of those children.

Ah, I might not be explaining the situation well. There are no assets with key of just

"grandparent"

or parent. Grandparent and parent are key prefixes for the actually assets, all of which are

["grandparent", "parent", "something"]

. So in my case I want to select every asset that has the key prefixes of

["grandparent", "parent"]

Oh, they're prefixes and not assets. That's my fault! Give me a second to give an actual answer then I really should have caught that while I was writing the code snippets.

The source code for AssetSelection showed a few examples. The worst case you can use AssetSelection.all() and filter down the result set of asset keys.
