Params & Catalog

This chapter takes a deeper look at the two data-holding structs that every pipeline uses: the params struct for read-only configuration and the catalog struct for datasets.

For the basics of how these are used in a pipeline, see A minimal pipeline. For YAML file loading and CLI overrides, see YAML Configuration.

• Parameters — Param<T>, nested parameter structs, and struct parameters
• Catalog — organizing datasets, nested catalogs, and naming conventions
