 Additional permissions are need to use Amazon Redshift clusters and Amazon Redshift serverless environments. For more information on how to add permissions to ETL jobs, see [Review IAM permissions needed for ETL jobs](https://docs.aws.amazon.com/glue/latest/ug/setting-up.html#getting-started-min-privs-job).

## Overview

 When adding an Amazon Redshift connection, you can choose an existing Amazon Redshift connection or create a new connection when adding a **Data source - Redshift** node in AWS Glue Studio. 

 AWS Glue supports both Amazon Redshift clusters and Amazon Redshift serverless environments. When you create a connection, Amazon Redshift serverless environments display the **serverless** label next to the connection option. 

 For more information on how to create a Amazon Redshift connection, see [ Moving data to and from Amazon Redshift](https://docs.aws.amazon.com/glue/latest/dg/aws-glue-programming-etl-redshift.html#aws-glue-programming-etl-redshift-using).
