I figured out how to do this in the playground, but I can't seem to get to that screen through the dagit ui. Had to force my way through an URL

maybe I'm using a pretty old version of dagit

I'm a bit puzzled by Dagit in general. I can get to the launchpad from the job tab, but in the launchpad I can only launch one partition at a time... If I hit Materialize All, there is a UI to select multiple partitions, but then there is no way to specify the parameters 😕 Selecting a subset of steps relies as well on a search convention that I found here, but still it would be much nicer to be able to visually select them. Maybe these are all issues related to the way I'm approaching the tool so I would like to hear from the team on how you tackle them 🙂

@Fabio Picchi you may find that creating jobs for subsets of assets is useful. e.g. this defines a job for materializing all assets, and another job for assets tagged with the "import_raw_data" group:

all_assets_job = define_asset_job(name="all_assets_job")
raw_data_job = define_asset_job(
    name="raw_data", selection=AssetSelection.groups("import_raw_data")
)

After you add the jobs to your

Definitions

you should be able to 'materialize all' a selected job in Dagit
