How to specify a dict config

[dagsir[bot]]

How do you specify the following schema configuration on an op():

config:
dict_config: { 'key1': { 'subkey1': 'value1', 'subkey2': 'value2' },
'key2': { 'subkey1': 'value1', 'subkey2': 'value2' } }

where key1 and key2 are user specific and not known. Looks like Selector does this but only allows one entry to be configured in yaml file. Looks like I can just call out a dict() but then the subdict is not validated, right?

You can use Map to define a config dict:

from dagster import Map

@op(config_schema={"dict_config ": Field(Map({str: int}})))
def my_op(context):
    print(context.op_config.items())
