Metadata-Driven Development

Spec-as-code capabilities native to Lakeflow Framework — how you express pipelines, manage schemas, reuse patterns, parameterize values, and validate specs before deploy.

Substitutions are the parameterization mechanism in the data flow spec (similar to bundle variable substitution). Their primary use is environment-specific values; see also Logical Environments.
