To make this concrete, I have 2 assets that both take in a

price

parameter:

@asset(config_schema={
    "price": float
})
def asset1(context):
    return context.op_config["price"] * 2

@asset(config_schema={
    "price": float
})
def asset2(context):
    return context.op_config["price"] / 2

And I want to have 2 asset-based jobs, each of which has a different default price configured. The first approach would look like this:

job1 = define_asset_job(
    name="job1",
    config={"ops": {
        "asset1": {"config": {"price": 1}},
        "asset2": {"config": {"price": 1}},
    }}
)

job2 = define_asset_job(
    name="job2",
    config={"ops": {
        "asset1": {"config": {"price": 2}},
        "asset2": {"config": {"price": 2}},
    }}
)

It's fine, but it's clunky. The same number must be repeated for both assets, which is also clunky for users who want to overwrite values in launchpad. Instead, I might define a simple config_mapping which only exposes a single price parameter:

@config_mapping(config_schema={
    "price": float
})
def shared_config(val):
    return {
        "ops": {
            "asset1": {"config": {"price": val["price"]}},
            "asset2": {"config": {"price": val["price"]}},
        }
    }

And I could put this into a job:

job1 = define_asset_job(
    name="job1",
    config=shared_config
)

But it's not clear to me how I would set different default values for

job1

and

job2

using this config_mapping
