Hi, Suppose I have assets A,B,C,D. B and C are produced by a multi-asset op and the lineage of Asset D is A->B->D. How can I materialize through UI Asset D and all its dependencies? I’m okay when trying to materialize B to materialize C as well.

Hi Said. In the asset graph view, you can manually select any number of assets to materialize. You can also use the asset subset selection tool to type in a particular asset and all of its upstream dependencies, and then click

Materialize All

(see the selection string

*asset_d

):

I kinda want Assets produced by

multi-Assets

to be wired together, when one is materialized everything is materialized. I don’t want to get this issue when I try to materialize B.

When building job, the AssetsDefinition 'stage' contains asset keys [AssetKey(['B', 'B']), AssetKey(['C', 'C'])], but attempted to select only [AssetKey(['B', 'B'])]

I want it to automatically materialize C as well. I don’t have the intention to do subsetting because one op will produce B and C.

I see. We currently don’t support this selection syntax in the UI right now. Do you mind filing an issue in Github as a feature request? cc @sean / @sandy in case I’m missing anything…

To clarify more the

multi-asset

outputs

dataset_B

and

dataset_C

. If I go to Assets and search for

dataset_D

and go to its lineage and I click materialize all to materialize

dataset_D

. I would get a failure. My expectations that the

op

stage_a

would run and materialize

dataset_B

and

dataset_C

.

hi @Said Mancouri - this is the current expected behavior - we want to err on the side of not accidentally materializing assets that the user hasn't explicitly said should be materialized that said, I think your feedback is reasonable that this is a poor experience. we could replace the error with some sort of warning or confirmation dialog. if you're up for filing an issue, I can punt it over to the UI folks
