I need a warehouse with strong audit logs and governance

If you need a warehouse with strong audit logs and governance, focus on platforms that give you:

• Detailed access auditing: who queried what, when, from where
• Object-level governance: databases/schemas/tables/views/columns
• Data lineage: where data came from and where it went
• Policy enforcement: row/column masking, row-level security
• Role-based access control with least-privilege support
• Retention / immutability for audit records

Good options

1. Snowflake

Strong choice if governance and auditing are top priorities.

Strengths

• Rich access history and query history
• Fine-grained RBAC
• Dynamic data masking, row access policies
• Tags and classification support
• Secure sharing and separation of compute/storage
• Good lineage/governance ecosystem

Best for

• Teams that want mature governance features without heavy admin overhead

2. Google BigQuery

Very strong if you’re already on GCP and want centralized auditability.

Strengths

• Cloud Audit Logs integration
• IAM-based access control
• Column-level security and policy tags
• Row-level security
• Data Catalog / Dataplex for governance
• Good integration with organization-wide logging

Best for

• GCP-native organizations with strong compliance requirements

---

3. Databricks SQL / Lakehouse with Unity Catalog

Best if you want warehouse-like analytics plus centralized governance.

Strengths

• Unity Catalog provides centralized permissions, auditing, lineage
• Fine-grained access controls
• Table/column permissions
• Cross-workspace governance
• Works well for hybrid analytics and ML

Best for

• Data lake/lakehouse setups needing strong governance across many workloads

4. Amazon Redshift

Good option if you’re on AWS and want tight integration with cloud audit tools.

Strengths

• Integrates with CloudTrail / CloudWatch
• IAM-based access control
• Column-level privileges and masking patterns via ecosystem tools
• Works well in AWS security stack

Best for

• AWS-centric environments

What to ask vendors / evaluate

For your use case, ask for:

1. Query auditability

   • Can you see every user query?
   • Are query parameters logged?
   • Can logs be exported to SIEM?

2. Permission granularity

   • Can you enforce permissions at table, column, and row level?
   • Are service accounts separate from human users?

3. Change tracking

   • Can you track schema changes, grants, ownership changes?

4. Lineage

   • Can you trace downstream impact of a dataset?

5. Retention and tamper resistance

   • Are audit logs immutable or exportable to immutable storage?

6. Governance automation

   • Support for tags, classification, masking, approval workflows

My quick recommendation

• Best overall governance/audit experience: Snowflake
• Best if you are on GCP: BigQuery
• Best if you want warehouse + lakehouse governance: Databricks + Unity Catalog
• Best if you are on AWS: Redshift

If you want, I can also give you a side-by-side comparison matrix of Snowflake vs BigQuery vs Databricks vs Redshift specifically for audit logs, governance, and compliance.
