Building Data 360 Clean Rooms: Zero-Copy Architecture

Salesforce's Data 360 Clean Rooms team built a privacy-safe data collaboration platform using a zero-copy federation model, where queries execute at the data source rather than moving raw data between systems. The architecture enforces GDPR and CCPA compliance through PII anonymization, aggregation thresholds, query frequency capping, and use case templates restricted to approved SQL patterns. A decoupled control plane enables 1:N scalability so one provider can collaborate with many consumers simultaneously while maintaining isolated governance contexts. Integration with external platforms like AWS Clean Rooms required building a secure interoperability layer for schema mapping and metadata coordination. Immutable audit logs and granular access controls ensure every collaboration remains auditable and governed.
