Dataplex And BigQuery Governance
Overview
Use this skill when governance on GCP is centered on Dataplex, BigQuery, and related Google Cloud metadata controls. It helps agents define governance zones, policy-tag boundaries, lineage expectations, and trusted publishing patterns for warehouse and lake platforms.
When to Use
- designing
Dataplex lakes, zones, or governance domains
- defining
BigQuery policy tags and governed publish boundaries
- improving metadata quality, lineage, and discovery on
GCP
- aligning warehouse and lake governance across
Cloud Storage, BigQuery, Dataflow, and Dataproc
- making governed analytics delivery work with regional or regulated-data controls
Do not treat BigQuery governance as only a permissions problem. Trusted publishing also needs metadata, ownership, and policy boundaries.
Workflow
Define the governance boundary.
Decide:
- lakes and zones
- datasets and domains
- producer versus consumer boundaries
- ownership expectations
Define metadata and policy controls.
Include:
- policy tags
- classifications
- lineage coverage
- discovery metadata
- trusted versus exploratory asset signaling
Align lake and warehouse governance.
Make explicit how Cloud Storage, BigQuery, and processing services fit the same control model.
Design governed publish behavior.
Require:
- clear serving boundaries
- ownership visibility
- release or validation evidence where needed
- rules for schema and policy change
Validate day-2 operations.
Review whether onboarding, schema evolution, and new domains remain manageable under the governance model.
Common Rationalizations
| Rationalization |
Reality |
| "Policy tags are the whole governance design." |
Tags help, but they do not replace ownership, zone design, trusted publishing, or metadata quality. |
| "Dataplex is only for lake governance." |
Many teams need a joined governance model across storage, warehouse, and processing surfaces. |
| "Discovery will happen automatically once assets are scanned." |
Useful discovery requires curated metadata and trust signals. |
Red Flags
- lake, dataset, and domain boundaries are inconsistent
- policy tags exist without ownership or publish context
- warehouse and lake governance behave differently with no clear rule
- certification or trusted-asset behavior is missing
- schema and policy changes are operationally unclear
