// BatchPutAttributes API operation for Amazon SimpleDB.

// 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.
//
// 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. This operation is vulnerable to exceeding the maximum URL size when making

// PutAttributes API operation for Amazon SimpleDB.
//
// 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.
//
// 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
//
// Returns awserr.Error for service API and SDK errors. Use runtime type assertions
// with awserr.Error's Code and Message methods to get detailed information about
// the error.
