dagster

hi I have asset defined from graph and wanted to use:
```from dagster import asset, AssetIn

@asset(ins={"stuff": AssetIn(metadata={"allow_missing_partitions": True})})
def use_stuff(context, stuff):
  stuff.keys()```
but can't find place to use it in `AssetsDefinition.from_graph` function. Anyone have similar problem. Is it even possible for asset from graph?

What I found is that I can define metadata in op definition and it works

Do you mean you want to define a dependency to / from `use_stuff` from the graph-backed asset?

If so, check out the `keys_by_input_name`/`keys_by_output_name` parameters

I wanted to pass {"allow_missing_partitions": True} metadata to input context to be used by io manager in `keys_by_input_name` I can only specify AssetKey not AssetIn where I can pass metadata
