When declaring a pipeline, can I also set some config values on solids? For example, with the following solid and pipeline, can I set the value of the
config to something like
as part of the pipeline, and still optionally set it via the environment when executing the pipeline?
Copy code
    config={'prefix': Field(str, is_optional=True, default_value='_')}
def prefix_value(context, v):
    return f'{context.solid_config["prefix"]}{v}'

def test_normalize():
    prefix_value.alias('prefix_foo')() # set prefix to _foo_ somehow?
    prefix_value.alias('prefix_bar')() # and, set prefix to _bar_ somehow?

We don’t currently support this but I actually think this is a really interesting idea.
We could support this with a mechanism similar to the “config_mapping” mechanism on composite_solids
