// Overview  This is an interface reference for Amazon Redshift. It contains
// documentation for one of the programming or command line interfaces you can
// use to manage Amazon Redshift clusters. Note that Amazon Redshift is asynchronous,
// which means that some interfaces may require techniques, such as polling
// or asynchronous callback handlers, to determine when a command has been applied.
// In this reference, the parameter descriptions indicate whether a change is
// applied immediately, on the next instance reboot, or during the next maintenance
// window. For a summary of the Amazon Redshift cluster management interfaces,
// go to Using the Amazon Redshift Management Interfaces  (http://docs.aws.amazon.com/redshift/latest/mgmt/using-aws-sdk.html).
//
//  Amazon Redshift manages all the work of setting up, operating, and scaling
// a data warehouse: provisioning capacity, monitoring and backing up the cluster,
// and applying patches and upgrades to the Amazon Redshift engine. You can
// focus on using your data to acquire new insights for your business and customers.
//
// If you are a first-time user of Amazon Redshift, we recommend that you begin
// by reading the The Amazon Redshift Getting Started Guide (http://docs.aws.amazon.com/redshift/latest/gsg/getting-started.html)
//
// If you are a database developer, the Amazon Redshift Database Developer
// Guide (http://docs.aws.amazon.com/redshift/latest/dg/welcome.html) explains
// how to design, build, query, and maintain the databases that make up your
// data warehouse.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
