In 2026, Amazon Redshift launched RG instance types in the AWS GovCloud (US-East and US-West) regions. These instances utilize AWS Graviton processors and provide significantly improved performance for data warehouse and data lake workloads, with claims of up to 2.4 times faster operation compared to the earlier RA3 generation, alongside a 30% reduction in price per vCPU.
The RG instances incorporate Redshift’s custom vectorized query engine optimized for formats like Apache Iceberg and Parquet, enabling unified SQL analytics across data warehouses and lakes. Available in multiple sizes and flexible payment options, customers can upgrade existing RA3 clusters to RG to benefit from performance and cost efficiencies in regulated cloud environments.
