/**
 * 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.
 * 

* Note: Do not directly implement this interface, new methods are added to it regularly. Extend from * {@link com.amazonaws.services.dynamodbv2.AbstractAmazonDynamoDBAsync} instead. *

*

* Amazon DynamoDB *

* 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. *

*

* 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. *

*

* 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. *

* A single operation can retrieve up to 16 MB of data, which can contain as many as 100 items. * BatchGetItem returns a partial result if the response size limit is exceeded, the table's * provisioned throughput is exceeded, or an internal processing failure occurs. If a partial result is returned, * the operation returns a value for UnprocessedKeys. You can use this value to retry the operation * starting with the next item to get. *

* *

* If you request more than 100 items, BatchGetItem returns a ValidationException with the * message "Too many items requested for the BatchGetItem call." *

*
*

* For example, if you ask to retrieve 100 items, but each individual item is 300 KB in size, the system returns 52 * items (so as not to exceed the 16 MB limit). It also returns an appropriate UnprocessedKeys value so * you can get the next page of results. If desired, your application can include its own logic to assemble the * pages of results into one dataset. *

*

* If none of the items can be processed due to insufficient provisioned throughput on all of the tables in * the request, then BatchGetItem returns a ProvisionedThroughputExceededException. If * at least one of the items is successfully processed, then BatchGetItem completes * successfully, while returning the keys of the unread items in UnprocessedKeys. *

* *

* If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we * strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation * immediately, the underlying read or write requests can still fail due to throttling on the individual tables.

* For more information, see Batch * Operations and Error Handling in the Amazon DynamoDB Developer Guide. *
