Network.AWS.SDB.BatchPutAttributes
Description
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 ItemName parameter.
The client may specify new attributes using a combination of the Name and 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 Name
and 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.
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 Name, Value, or 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
