Which AWS service does the AWS SDK for Ruby NOT support?

The AWS SDK for Ruby is designed to provide developers with tools and libraries to interact with various AWS services. It supports a wide range of AWS services, including storage, compute, database, and others. However, Amazon Redshift is a managed data warehouse service that is not directly supported by the AWS SDK for Ruby in the same way that other services like S3, EC2, and DynamoDB are.

The AWS SDK for Ruby allows seamless interaction with S3 for storage, EC2 for compute instances, and DynamoDB for NoSQL database interactions, providing specific methods and features tailored to these services. In contrast, while it may be possible to interact with Amazon Redshift through alternative means like JDBC or by executing SQL commands, the direct SDK functionality and convenience features unique to the SDK are not present for Redshift.

This distinction highlights the specific capabilities and limitations of the SDK in terms of service support, making it clear why Amazon Redshift falls outside the direct service coverage of the AWS SDK for Ruby.
