/**
 * 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 AWS 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 AWS region, * providing built-in high availability and data durability. *

* The BatchGetItem operation returns the attributes of one or more items from one or more tables. You * identify requested items by primary key. *

*

* A single operation can retrieve up to 16 MB of data, which can contain as many as 100 items. * BatchGetItem will return 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 will return 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 data set. *

*

* If none of the items can be processed due to insufficient provisioned throughput on all of the tables in * the request, then BatchGetItem will return 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. If * you delay the batch operation using exponential backoff, the individual requests in the batch are much more * likely to succeed. *

*

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

*
*

* By default, BatchGetItem performs eventually consistent reads on every table in the request. If you * want strongly consistent reads instead, you can set ConsistentRead to true for any or * all tables. *

*

* In order to minimize response latency, BatchGetItem retrieves items in parallel. *

*

* When designing your application, keep in mind that DynamoDB does not return items in any particular order. To * help parse the response by item, include the primary key values for the items in your request in the * ProjectionExpression parameter. *

*

* If a requested item does not exist, it is not returned in the result. Requests for nonexistent items consume the * minimum read capacity units according to the type of read. For more information, see Capacity Units Calculations in the Amazon DynamoDB Developer Guide. *

    * Call DescribeLimits for a particular region to obtain your current account limits on provisioned * capacity there. *

    *

    * Create a variable to hold the aggregate read capacity units provisioned for all your tables in that region, and * one to hold the aggregate write capacity units. Zero them both. *

    *
  4. *
  5. *

    * Call ListTables to obtain a list of all your DynamoDB tables. *

    *
  6. *
  7. *

    * For each table name listed by ListTables, do the following: *

    *
      *
    • *

      * Call DescribeTable with the table name. *

      *
    • *
    • *

      * Use the data returned by DescribeTable to add the read capacity units and write capacity units * provisioned for the table itself to your variables. *

      *
    • *
    • *

      * If the table has one or more global secondary indexes (GSIs), loop over these GSIs and add their provisioned * capacity values to your variables as well. *

      *
    • *
    *
  8. *
  9. *

    * Report the account limits for that region returned by DescribeLimits, along with the total current * provisioned capacity levels you have calculated. *

    *
  10. *
*

* This will let you see whether you are getting close to your account-level limits. *

*

* The per-table limits apply only when you are creating a new table. They restrict the sum of the provisioned * capacity of the new table itself and all its global secondary indexes. *

*

* For existing tables and their GSIs, DynamoDB will not let you increase provisioned capacity extremely rapidly, * but the only upper limit that applies is that the aggregate provisioned capacity over all your tables and GSIs * cannot exceed either of the per-account limits. *
