Another solution is to use a new utility developed in collaboration with a customer that utilizes Amazon Redshift Data Sharing. This will unload the data in question to S3 and then load the data using COPY. Create RoleB, an IAM role in the Amazon Redshift account with permissions to assume RoleA.ģ.
