AWS Java SDK - V2 support for the Redshift JDBC Driver

Currently, the Amazon Redshift JDBC driver is designed to work with AWS SDK for Java version 1.x. There is no official announcement or information available about updating the Redshift JDBC driver to support the AWS SDK for Java version 2.x.

However, it's important to note that the AWS SDK for Java 2.x does provide support for interacting with Amazon Redshift through its own set of clients. Specifically, the SDK offers RedshiftClient for managing Redshift clusters and RedshiftDataClient for working with data in Redshift. These clients allow developers to perform various operations on Redshift databases using the latest SDK version.

For applications that specifically require JDBC connectivity, the current recommendation is to continue using the Redshift JDBC driver with AWS SDK for Java 1.x. If you need to use AWS SDK for Java 2.x in your project while also using JDBC connectivity to Redshift, you may need to manage both SDK versions in your project dependencies.

As AWS continues to develop and improve their services, it's possible that future updates may include support for AWS SDK for Java 2.x in the Redshift JDBC driver. However, as of now, there is no official information available about such an update.
