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.
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:
BatchPutAttributes operationThis is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginBatchPutAttributes and EndBatchPutAttributes.
