AWS Clean Rooms adds minimum aggregation thresholds to custom analysis rules
AWS Clean Rooms now supports minimum aggregation thresholds for its Custom analysis rule type, allowing organizations to enforce privacy-protecting aggregation on custom SQL queries. This enhancement helps prevent queries from returning results about individuals or small groups by ensuring each output row represents a specified minimum number of distinct values. Data providers can configure these thresholds without relying on pre-approved templates or manual code reviews, streamlining secure data collaboration. The feature also allows specifying which columns can be filtered or joined across datasets.

AWS Clean Rooms now allows data providers to apply minimum aggregation thresholds directly within custom analysis rules. This ensures privacy by preventing queries from revealing data about individuals or small groups, without requiring pre-approved templates or manual code reviews. Users can define identity columns and minimum counts for specific columns and specify which columns can be filtered or joined across datasets.
