Amazon Redshift now supports federated permissions across multi-warehouse architectures

Amazon Redshift now supports federated permissions, which simplify permissions management across multiple Redshift data warehouses. Customers are adopting multi-warehouse architectures to scale and isolate workloads and are looking for simplified, consistent permissions management across warehouses. With Redshift federated permissions, you define data permissions once from any Redshift warehouse and automatically enforce them across all warehouses in the account.

Amazon Redshift warehouses with federated permissions are auto-mounted in every Redshift warehouse, and you can use existing workforce identities with AWS IAM Identity Center or use existing IAM roles to query data across warehouses. Regardless of which warehouse is used for querying, row-level, column-level, and masking controls always apply automatically, delivering fine-grained access compliance. You can get started by registering a Redshift Serverless namespace or Redshift provisioned cluster with AWS Glue Data Catalog and start querying across warehouses using Redshift Query Editor V2, or any supported SQL client. You get horizontal scalability with multiple warehouses by allowing you to add new warehouses without increasing governance complexity, as new warehouses automatically enforce permission policies and analysts immediately see all databases from registered warehouses.

Amazon Redshift federated permissions is available at no additional cost in supported AWS regions. To learn more, visit the Amazon Redshift documentation.
