/**
* Asynchronous client for accessing AmazonSimpleDB.
* All asynchronous calls made using this client are non-blocking. Callers could either
* process the result and handle the exceptions in the worker thread by providing a callback handler
* when making the call, or use the returned Future object to check the result of the call in the calling thread.
* Amazon SimpleDB
* 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.
*
*
* 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.
*
*
* Visit
* http://aws.amazon.com/simpledb/
* for more information.

*
* The PutAttributes operation creates or replaces attributes in an

* parameters. The client specifies the first attribute by the parameters
* Attribute.0.Name and Attribute.0.Value , the
* second attribute by the parameters Attribute.1.Name and
* Attribute.1.Value , and so on.
*
*
* Attributes are uniquely identified in an item by their name/value
* combination. For example, a single item can have the attributes
* { "first_name", "first_value" } and { "first_name",
* second_value" } . However, it cannot have two attribute
* instances where both the Attribute.X.Name and
* Attribute.X.Value are the same.
*
*
* Optionally, the requestor can supply the Replace
* parameter for each individual attribute. Setting this value to
* true causes the new attribute value to replace the
* existing attribute value(s). For example, if an item has the
* attributes { 'a', '1' } , { 'b', '2'} and
* { 'b', '3' } and the requestor calls
* PutAttributes using the attributes { 'b', '4'
* } with the Replace parameter set to true, the
* final attributes of the item are changed to { 'a', '1' }
* and { 'b', '4' } , which replaces the previous values of
* the 'b' attribute with the new value.
*
*
* NOTE: Using PutAttributes to replace attribute values that do
* not exist will not result in an error response.
*
*
* You cannot specify an empty string as an attribute name.
*
*
* Because Amazon SimpleDB makes multiple copies of client data and uses
* an eventual consistency update model, an immediate GetAttributes or
* Select operation (read) immediately after a PutAttributes or
* DeleteAttributes operation (write) might not return the updated data.
*
*
* The following limitations are enforced for this operation:
*
* - 256 total attribute name-value pairs per item
* - One billion attributes per domain
* - 10 GB of total user data storage per domain
*

* This helps yield savings in round trips and latencies, enabling
* Amazon SimpleDB to optimize requests and generally produce better
* throughput.
*
*
* The client may specify the item name with the
* Item.X.ItemName parameter. The client may specify new
* attributes using a combination of the
* Item.X.Attribute.Y.Name and
* Item.X.Attribute.Y.Value parameters. The client may
* specify the first attribute for the first item using the parameters
* Item.0.Attribute.0.Name and
* Item.0.Attribute.0.Value , and for the second attribute
* for the first item by the parameters
* Item.0.Attribute.1.Name and
* Item.0.Attribute.1.Value , and so on.
*
*
* Attributes are uniquely identified within an item by their name/value
* combination. For example, a single item can have the attributes
* { "first_name", "first_value" } and { "first_name",
* "second_value" } . However, it cannot have two attribute
* instances where both the Item.X.Attribute.Y.Name and
* Item.X.Attribute.Y.Value are the same.
*
*
* Optionally, the requester can supply the Replace
* parameter for each individual value. Setting this value to
* true will cause the new attribute values to replace the
* existing attribute values. For example, if an item I has
* the attributes { 'a', '1' }, { 'b', '2'} and { 'b',
* '3' } and the requester does a BatchPutAttributes of
* {'I', 'b', '4' } with the Replace parameter set to true,
* the final attributes of the item will be { 'a', '1' } and
* { 'b', '4' } , replacing the previous values of the 'b'
* attribute with the new value.
*
*
* NOTE: 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.
*
*
* IMPORTANT: 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.
*
*
* You can execute multiple BatchPutAttributes operations
* and other operations in parallel. However, large numbers of concurrent
* BatchPutAttributes calls can result in Service
* Unavailable (503) responses.
*
*
* The following limitations are enforced for this operation:
*
* - 256 attribute name-value pairs per item
* - 1 MB request size
* - 1 billion attributes per domain
* - 10 GB of total user data storage per domain
* - 25 item limit per
