hey, on kedro, version 0.19.12 whats the best way to use a parameter to overwrite part of the catalog and catalog_globals paths?

Hi Gauthier, You can either use interpolation: https://docs.kedro.org/en/0.19.12/configuration/advanced_configuration.html#catalog Or use globals: https://docs.kedro.org/en/0.19.12/configuration/advanced_configuration.html#how-to-use-global-variables-with-the-omegaconfigloader or if you want to use run time parameters to overwrite something: https://docs.kedro.org/en/0.19.12/configuration/advanced_configuration.html#how-to-override-configuration-with[…]rameters-with-the-omegaconfigloader

many thanks @Ankita Katiyar the problem is that I wanted to use a parameter for interpolation into catalog_globals and then into catalog, to be able to use

kedro run --params my_dataset_path=xx

but it doesnt seem to be supported directly? instead i now use

MY_DATASET_PATH=xx kedro run

, after adding this in settings.py

OmegaConf.register_new_resolver("env", lambda var, default=None: os.getenv(var, default))

, which interpolates directly into catalog_globals without a parameter. I would still prefer to use a parameter rather than an envvar if possible, what do you recommend?

I think for that you could use

runtime_params:

resolver. https://docs.kedro.org/en/0.19.12/configuration/advanced_configuration.html#how-to-override-configuration-with[…]rameters-with-the-omegaconfigloader Then your catalog entry should look like:

my_dataset:
  type: <type>
  filepath: "data/01_raw/${runtime_params:path}"

And you could run with

kedro run --params path=path

great, thx
