/**
* Container for the parameters to the {@link com.amazonaws.services.simpledb.AmazonSimpleDB#batchPutAttributes(BatchPutAttributesRequest) BatchPutAttributes operation}.
*
* The BatchPutAttributes operation creates or replaces
* attributes within one or more items. By using this operation, the
* client 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.
*
*
* 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
BatchPutAttributes operation
*
