AWS Clean Rooms supports adding new data providers to existing collaborations

AWS Clean Rooms now allows customers to add new data providers to existing collaborations, providing more flexibility in data partnerships and analysis.

• Customers can add new data provider members to an existing collaboration without creating a new one
• Collaboration owners can configure new members with data-only contributions
• Existing privacy controls remain intact when adding new members
• New data providers' additions are tracked in the change history for transparency
• Example use case: A publisher can enable a measurement company to join a collaboration with an advertiser

This feature reduces onboarding time and allows for more dynamic data collaboration while maintaining strong privacy protections.
