Variable library editor

What this editor does

A Variable library is a centralized name-to-value store with value sets per environment (dev/test/prod). In Loom it is workspace- or domain-scoped and used for pipeline, notebook, and SQL parameter substitution.

Getting started

  1. Define variables — Add named variables with a default value.
  2. Add value sets — Create per-environment value sets (dev/test/prod) that override defaults.
  3. Reference from items — Use variables in pipelines, notebooks, and SQL via parameter substitution.
  4. Promote across stages — Switch the active value set when deploying between environments.
