AWS Clean Rooms supports minimum aggregation thresholds in custom analysis rules

AWS Clean Rooms now supports minimum aggregation thresholds for the Custom analysis rule type, enabling privacy-preserving collaborative data analysis.

• Enforce minimum aggregation on custom SQL queries to prevent results about individuals or small groups
• Data providers specify identity columns and minimum identity counts without pre-approved templates
• Eliminates need for manual code reviews before queries execute
• Configure which columns can be filtered or joined across datasets
• Example: Filter rural zip codes with fewer than 1,000 common users for privacy protection

This enhancement simplifies privacy-compliant data collaboration by allowing ad-hoc queries with automatic aggregation enforcement.
