Considerations for data sharing in
Amazon Redshift
With Amazon Redshift data sharing, you can securely share access to live data across Amazon Redshift clusters, workgroups, AWS accounts, and AWS Regions without manually moving or copying the data. Previously, objects in datashares were read only in all circumstances. Writing to an object in a datashare is a new feature. Objects in datashares are only write-enabled when a producer specifically grants write privileges like INSERT or CREATE on objects to the datashare. Additionally, for cross-account sharing, a producer has to authorize the datashare for writes and the consumer has to associate specific clusters and workgroups for writes.
This section covers considerations when working with Amazon Redshift data sharing.
