Choose Policies, and then choose Create policy.ģ. Create an IAM role in the account that's using Amazon S3 (RoleA)Ģ. The target for these files in this example is the Amazon Redshift table cabsalesdata. Each folder has similar data but for different customers.

We can use the COPY command with the JOB parameter to automate this ingestion process.

Note: These steps work regardless of your data format. Test the cross-account access between RoleA and RoleB. Create RoleB, an IAM role in the Amazon Redshift account with permissions to assume RoleA.ģ.

Create RoleA, an IAM role in the Amazon S3 account.Ģ. These steps apply to both Redshift Serverless and Redshift provisioned data warehouse:ġ. To access Amazon S3 resources that are in a different account from where Amazon Redshift is in use, perform the following steps.
