Amazon Redshift Data Sharing, a secure way to share live data across Amazon Redshift clusters, is now available in AWS China regions. Customers can now share data to provisioned clusters and serverless workgroups in the same account and different accounts, as long as they are within the same region. Redshift Data Sharing enables instant, granular, and high-performance data access across Redshift clusters without the need to copy or move data. Redshift Data Sharing provides live access to the data so that your users always see the most up-to-date and consistent information as it is updated in the data warehouse. Redshift Data Sharing can be used on your Amazon Redshift RA3 clusters at no additional cost.
