/**
* Container for the parameters to the {@link com.amazonaws.services.simpledb.AmazonSimpleDB#putAttributes(PutAttributesRequest) PutAttributes operation}.
*
* The PutAttributes operation creates or replaces attributes in an
* item. The client may specify new attributes using a combination of the
* Attribute.X.Name and Attribute.X.Value
* 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
*
*
