TL;DR: Business context, lineage, ownership and compliance can stay aligned across an open lakehouse through bi-directional metadata synchronization between Collibra and Google Cloud Knowledge Catalog, so data teams can trust what they are using for AI and operational decisions, according to Collibra. The practical issue is not catalog coverage alone, but whether governance and technical reality stay synchronized as data estates change.
Editorial analysis by NHI Mgmt Group, based on content published by Collibra: “Google Cloud And Collibra Deepen Partnership To Bring Business Context And Semantics Directly To Knowledge Catalog”.
Key questions
Q: How should teams govern metadata in open lakehouse environments?
A: Teams should govern metadata as a live control surface, not a static catalogue.
Q: Why does stale metadata create risk for AI and analytics decisions?
A: Stale metadata causes teams to approve or consume data based on outdated lineage, ownership or quality assumptions.
Q: What are the signs that a data catalog is out of sync with the lakehouse?
A: Common signs include mismatched ownership, lineage that no longer reflects platform changes, inconsistent definitions across teams and compliance context that is missing from active workflows.
Practitioner guidance
- Map authoritative metadata flows across the lakehouse Identify where business context is created, where technical discovery is produced and which system is the source of record for each metadata class.
- Test for metadata drift after platform changes Compare the governed catalog to the actual cloud discovery state after ingestion, schema, ownership or workspace changes.
- Embed governance context in consuming workflows Make sure users can see ownership, definitions and compliance context inside the analytics and data engineering workflows they already use, rather than forcing a separate governance lookup.
Bottom line: Bi-directional metadata governance helps keep open lakehouse context aligned with platform reality, which is essential when multiple teams depend on the same data assets.

Bi-directional metadata sync is becoming a control boundary, not a convenience feature. When governance data flows in both directions, the organisation is no longer relying on periodic manual reconciliation to maintain trust. That changes the operating model for data, AI and identity teams because the control record can remain closer to the technical estate. The implication is that metadata drift should be treated as governance failure, not housekeeping.
A few things that frame the scale:
- The average organisation believes more than 1 in 5 of their non-human identities are insufficiently secured, according to The 2024 ESG Report: Managing Non-Human Identities.
- Enterprises that have experienced a compromised NHI averaged 2.7 separate incidents in the past 12 months, according to Oasis Security & ESG.
A question worth separating out:
Q: How do security and data teams know whether governance controls are actually working?
A: They should test whether metadata changes, ownership updates and discovery signals are reflected consistently across both the governance platform and the cloud environment. If current state cannot be reconstructed from both sources, the control is not functioning as intended.

Bi-directional metadata sync is becoming a governance control, not an integration detail. In open lakehouse architectures, the organisation cannot rely on a one-way catalog if technical reality is changing underneath it. When governed context is pushed into the data fabric and discovery is fed back into the system of record, the enterprise can make lineage, ownership and policy decisions against the same truth. The practitioner conclusion is straightforward: treat synchronisation as part of governance design, not as an afterthought.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: When should organisations prioritise metadata synchronisation over more catalog coverage?
A: Prioritise synchronisation when the catalogue already exists but users still cannot trust it after platform changes. Adding more records does not solve drift. The real problem is whether governed context and technical discovery stay connected well enough for teams to rely on the system during daily operations.
