* <p>
* Amazon SimpleDB <p>
* Amazon SimpleDB is a web service providing the core database
* functions of data indexing and querying in the cloud. By offloading
* the time and effort associated with building and operating a web-scale
* database, SimpleDB provides developers the freedom to focus on
* application development.
* </p>
* <p>
* A traditional, clustered relational database requires a sizable
* upfront capital outlay, is complex to design, and often requires
* extensive and repetitive database administration. Amazon SimpleDB is
* dramatically simpler, requiring no schema, automatically indexing your
* data and providing a simple API for storage and access. This approach
* eliminates the administrative burden of data modeling, index
* maintenance, and performance tuning. Developers gain access to this
* functionality within Amazon's proven computing environment, are able
* to scale instantly, and pay only for what they use.
* </p>

* <code>Attribute.1.Value</code> , and so on.

* Attributes are uniquely identified in an item by their name/value

* <code>{ 'b', '3' }</code> and the requestor calls
* <code>PutAttributes</code> using the attributes <code>{ 'b', '4'

* <code>Item.0.Attribute.1.Value</code> , and so on.
* </p>
* <p>
* Attributes are uniquely identified within an item by their name/value
* combination. For example, a single item can have the attributes
* <code>{ "first_name", "first_value" }</code> and <code>{ "first_name",
* "second_value" }</code> . However, it cannot have two attribute
* instances where both the <code>Item.X.Attribute.Y.Name</code> and
* <code>Item.X.Attribute.Y.Value</code> are the same.
* </p>
* <p>
* Optionally, the requester can supply the <code>Replace</code>
* parameter for each individual value. Setting this value to
* <code>true</code> will cause the new attribute values to replace the
* existing attribute values. For example, if an item <code>I</code> has
* the attributes <code>{ 'a', '1' }, { 'b', '2'}</code> and <code>{ 'b',
* '3' }</code> and the requester does a BatchPutAttributes of
* <code>{'I', 'b', '4' }</code> with the Replace parameter set to true,
* the final attributes of the item will be <code>{ 'a', '1' }</code> and
* <code>{ 'b', '4' }</code> , replacing the previous values of the 'b'
* attribute with the new value.
* </p>
* <p>
* <b>NOTE:</b> You cannot specify an empty string as an item or as an
* attribute name. The BatchPutAttributes operation succeeds or fails in
* its entirety. There are no partial puts.
* </p>
* <p>
* <b>IMPORTANT:</b> This operation is vulnerable to exceeding the
* maximum URL size when making a REST request using the HTTP GET method.
* This operation does not support conditions using Expected.X.Name,
* Expected.X.Value, or Expected.X.Exists.
* </p>
* <p>
* You can execute multiple <code>BatchPutAttributes</code> operations
* and other operations in parallel. However, large numbers of concurrent
* <code>BatchPutAttributes</code> calls can result in Service
* Unavailable (503) responses.
* </p>
* <p>
* The following limitations are enforced for this operation:
* <ul>
* <li>256 attribute name-value pairs per item</li>
* <li>1 MB request size</li>
* <li>1 billion attributes per domain</li>
* <li>10 GB of total user data storage per domain</li>
* <li>25 item limit per <code>BatchPutAttributes</code> operation</li>
