Core Concepts
These pages define the vocabulary used across tablespec. They are written for technical readers who understand tables and pipelines but may be new to UMF, ingested bronze, Great Expectations, dbt, or Databricks Lakeflow.
Defines the three layers tablespec compiles: raw records for audit, ingested bronze for source-table contracts, and silver for declared business decisions.
Explains the separate UMF project, tablespec’s pipeline extension, shared documents, and legacy table-spec compatibility.
Defines the reusable catalog of generated files: SQL DDL, ingest SQL, PySpark and JSON schemas, Great Expectations suites, dbt projects, and Lakeflow pipelines.
Defines how generated Great Expectations suites run against raw records and typed ingested tables, including Databricks serverless behavior.
