   # Comma-separated list of the datasets for which we support dataset scripts.
   # Unix shell-style wildcards also work in the dataset name for namespaced datasets, for example `some_namespace/*` to refer to all the datasets in the `some_namespace` namespace.
   # The keyword `{{ALL_DATASETS_WITH_NO_NAMESPACE}}` refers to all the datasets without namespace.
