/**
 * Interface for accessing DynamoDB 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>
 * <b>Note:</b> Do not directly implement this interface, new methods are added to it regularly. Extend from
 * {@link com.amazonaws.services.dynamodbv2.AbstractAmazonDynamoDBAsync} instead.
 * </p>
 * <p>
 * <fullname>Amazon DynamoDB</fullname>
 * <p>
 * Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with
 * seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed
 * database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software
 * patching, or cluster scaling.
 * </p>
 * <p>
 * With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of
 * request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance
 * degradation, and use the Amazon Web Services Management Console to monitor resource utilization and performance
 * metrics.
 * </p>
 * <p>
 * DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle
 * your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is
 * stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an Amazon Web
 * Services Region, providing built-in high availability and data durability.
 * </p>

     * <p>
     * With <code>BatchWriteItem</code>, you can efficiently write or delete large amounts of data, such as from Amazon
     * EMR, or copy data from another database into DynamoDB. In order to improve performance with these large-scale
     * operations, <code>BatchWriteItem</code> does not behave in the same way as individual <code>PutItem</code> and
     * <code>DeleteItem</code> calls would. For example, you cannot specify conditions on individual put and delete
     * requests, and <code>BatchWriteItem</code> does not return deleted items in the response.
     * </p>
     * <p>
     * If you use a programming language that supports concurrency, you can use threads to write items in parallel. Your
     * application must include the necessary logic to manage the threads. With languages that don't support threading,
     * you must update or delete the specified items one at a time. In both situations, <code>BatchWriteItem</code>
     * performs the specified put and delete operations in parallel, giving you the power of the thread pool approach
     * without having to introduce complexity into your application.
     * </p>
     * <p>
     * Parallel processing reduces latency, but each specified put and delete request consumes the same number of write
     * capacity units whether it is processed in parallel or not. Delete operations on nonexistent items consume one
     * write capacity unit.
     * </p>
     * <p>
     * If one or more of the following is true, DynamoDB rejects the entire batch write operation:
     * </p>
     * <ul>
     * <li>
     * <p>
     * One or more tables specified in the <code>BatchWriteItem</code> request does not exist.

     * <p>

     * primary key schema.
     * </p>
     * </li>
     * <li>
     * <p>
     * You try to perform multiple operations on the same item in the same <code>BatchWriteItem</code> request. For
     * example, you cannot put and delete the same item in the same <code>BatchWriteItem</code> request.
     * </p>
     * </li>

     * <p>
     * With <code>BatchWriteItem</code>, you can efficiently write or delete large amounts of data, such as from Amazon
     * EMR, or copy data from another database into DynamoDB. In order to improve performance with these large-scale
     * operations, <code>BatchWriteItem</code> does not behave in the same way as individual <code>PutItem</code> and
     * <code>DeleteItem</code> calls would. For example, you cannot specify conditions on individual put and delete
     * requests, and <code>BatchWriteItem</code> does not return deleted items in the response.
     * </p>
     * <p>
     * If you use a programming language that supports concurrency, you can use threads to write items in parallel. Your
     * application must include the necessary logic to manage the threads. With languages that don't support threading,
     * you must update or delete the specified items one at a time. In both situations, <code>BatchWriteItem</code>
     * performs the specified put and delete operations in parallel, giving you the power of the thread pool approach
     * without having to introduce complexity into your application.
     * </p>
     * <p>
     * Parallel processing reduces latency, but each specified put and delete request consumes the same number of write
     * capacity units whether it is processed in parallel or not. Delete operations on nonexistent items consume one
     * write capacity unit.
     * </p>
     * <p>
     * If one or more of the following is true, DynamoDB rejects the entire batch write operation:
     * </p>
     * <ul>
     * <li>
     * <p>
     * One or more tables specified in the <code>BatchWriteItem</code> request does not exist.
     * </p>
     * </li>
     * <li>
     * <p>
     * Primary key attributes specified on an item in the request do not match those in the corresponding table's
     * primary key schema.
     * </p>
     * </li>
     * <li>
     * <p>
     * You try to perform multiple operations on the same item in the same <code>BatchWriteItem</code> request. For
     * example, you cannot put and delete the same item in the same <code>BatchWriteItem</code> request.
     * </p>
     * </li>
     * <li>
     * <p>
     * Your request contains at least two items with identical hash and range keys (which essentially is two put
     * operations).
     * </p>
     * </li>
     * <li>
     * <p>
     * There are more than 25 requests in the batch.
     * </p>
     * </li>
     * <li>
     * <p>
     * Any individual item in a batch exceeds 400 KB.
     * </p>
     * </li>
     * <li>
     * <p>
     * The total request size exceeds 16 MB.

     * <li>

     * <p>
