Amazon Redshift rg.large instances, powered by AWS Graviton processors, now support single-node clusters. Single-node support for rg.large clusters is available on P204 or later patch versions. Customers can now create a single-node rg.large cluster for smaller workloads that do not require high availability, offering a cost-effective option to conduct proofs of concept and tests quickly.

RG instances deliver up to 2.4x faster performance running data warehouse and data lake workloads when compared to previous generation RA3 instances, at 30% lower price per vCPU. RG instances include Redshift's custom-built vectorized data lake query engine that processes Apache Iceberg and Parquet data on your cluster nodes, turning on SQL analytics across your data warehouse and data lake using a single engine.

These RG instances are available in the following AWS Regions: Africa (Cape Town), Asia Pacific (Hong Kong), Asia Pacific (Tokyo), Asia Pacific (Seoul), Asia Pacific (Osaka), Asia Pacific (Mumbai), Asia Pacific (Hyderabad), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Jakarta), Asia Pacific (Melbourne), Asia Pacific (Malaysia), Asia Pacific (Taipei), Asia Pacific (Thailand), Canada (Central), Europe (Frankfurt), Europe (Stockholm), Europe (Spain), Europe (Ireland), Europe (London), Europe (Paris), South America (São Paulo), US East (N. Virginia), US East (Ohio), US West (N. California), US West (Oregon), AWS GovCloud (US-East), AWS GovCloud (US-West) and Mexico (Central).
