Minimum aggregation thresholds ensure queries do not return data about individuals or small groups by requiring a minimum number of distinct identities represented in query results. Organizations can set these thresholds per identity column and optionally impose stricter limits on specific fields, preventing privacy risks from granular data outcomes.
This advancement removes the need for manual code review or pre-approved templates when running custom SQL queries, enabling more flexible, privacy-preserving collaboration across datasets. It supports filtering or restricting joins on specific columns to comply with privacy policies in multi-party environments.
