/**
 * Client for accessing Amazon RDS asynchronously. Each asynchronous method will return a Java Future object
 * representing the asynchronous operation; overloads which accept an {@code AsyncHandler} can be used to receive
 * notification when an asynchronous operation completes.
 * <p>
 * <fullname>Amazon Relational Database Service</fullname>
 * <p>
 * </p>
 * <p>
 * Amazon Relational Database Service (Amazon RDS) is a web service that makes it easier to set up, operate, and scale a
 * relational database in the cloud. It provides cost-efficient, resizable capacity for an industry-standard relational
 * database and manages common database administration tasks, freeing up developers to focus on what makes their
 * applications and businesses unique.
 * </p>
 * <p>
 * Amazon RDS gives you access to the capabilities of a MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, Oracle, or
 * Amazon Aurora database server. These capabilities mean that the code, applications, and tools you already use today
 * with your existing databases work with Amazon RDS without modification. Amazon RDS automatically backs up your
 * database and maintains the database software that powers your DB instance. Amazon RDS is flexible: you can scale your
 * database instance's compute resources and storage capacity to meet your application's demand. As with all Amazon Web
 * Services, there are no up-front investments, and you pay only for the resources you use.
 * </p>
 * <p>
 * This interface reference for Amazon RDS contains documentation for a programming or command line interface you can
 * use to manage Amazon RDS. Note that Amazon RDS is asynchronous, which means that some interfaces might require
 * techniques such as polling or callback functions to determine when a command has been applied. In this reference, the
 * parameter descriptions indicate whether a command is applied immediately, on the next instance reboot, or during the
 * maintenance window. The reference structure is as follows, and we list following some related topics from the user
 * guide.
