batch-put-attributes

Description

The batch-put-attributes 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 batch-put-attributes 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.

Warning

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 batch-put-attributes operations and other operations in parallel. However, large numbers of concurrent batch-put-attributes 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 batch-put-attributes operation

Options

--domain-name (string) The name of the domain in which the attributes are being stored.

--items (list) A list of items on which to perform the operation.

Shorthand Syntax:

Name=string,Attributes=[{Name=string,Value=string,Replace=boolean},{Name=string,Value=string,Replace=boolean}] ...

JSON Syntax:

[
  {
    "Name": "string",
    "Attributes": [
      {
        "Name": "string",

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Output

None
