-- 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.
--
-- /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
