   :description: Complete lookup reference for Lakehouse Plumber — CLI, Python API, action options, error codes, configuration schemas, and the glossary.

Pure lookup. The CLI and Python API pages are generated from the code itself;
the action and configuration pages are option tables. For how to use any of this
and the reasoning behind it, see the :doc:`guides </guides/index>` and
:doc:`concepts </concepts/index>`.
