/**
* Client for accessing Amazon SimpleDB. All service calls made using this
* client are blocking, and will not return until the service call completes.
*
* 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 BatchPutAttributes operation creates or replaces

* can perform multiple PutAttribute operation with a single call.
* 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.
*
* 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

*
* The Select operation returns a set of attributes for
* ItemNames that match the select expression.
* Select is similar to the standard SQL SELECT statement.
*
*
* The total size of the response cannot exceed 1 MB in total size. Amazon
* SimpleDB automatically adjusts the number of items returned per page to
* enforce this limit. For example, if the client asks to retrieve 2500
* items, but each individual item is 10 kB in size, the system returns 100
* items and an appropriate NextToken so the client can access
* the next page of results.
*
*
* For information on how to construct select expressions, see Using Select
* to Create Amazon SimpleDB Queries in the Developer Guide.
*
*
* @param selectRequest
* @return Result of the Select operation returned by the service.
* @throws InvalidParameterValueException
* The value for a parameter is invalid.
* @throws InvalidNextTokenException
* The specified NextToken is not valid.
* @throws InvalidNumberPredicatesException
* Too many predicates exist in the query expression.
* @throws InvalidNumberValueTestsException
* Too many predicates exist in the query expression.
* @throws InvalidQueryExpressionException
* The specified query expression syntax is not valid.
* @throws MissingParameterException
* The request must contain the specified missing parameter.
* @throws NoSuchDomainException
* The specified domain does not exist.
* @throws RequestTimeoutException
* A timeout occurred when attempting to query the specified domain
* with specified query expression.
* @throws TooManyRequestedAttributesException
* Too many attributes requested.
