aws dynamodb transact-get-items
TransactGetItems is a synchronous operation that atomically retrieves multiple items from one or more tables (but not from indexes) in a single account and Region. A TransactGetItems call can contain up to 25 TransactGetItem objects, each of which contains a Get structure that specifies an item to retrieve from a table in the account and Region. A call to TransactGetItems cannot retrieve items from tables in more than one AWS account or Region. The aggregate size of the items in the transaction cannot exceed 4 MB. DynamoDB rejects the entire TransactGetItems request if any of the following is true: A conflicting operation is in the process of updating an item to be read. There is insufficient provisioned capacity for the transaction to be completed. There is a user error, such as an invalid data format. The aggregate size of the items in the transaction cannot exceed 4 MB
Options
| Name | Description |
|---|---|
--transact-items <list> | An ordered array of up to 25 TransactGetItem objects, each of which contains a Get structure |
--return-consumed-capacity <string> | A value of TOTAL causes consumed capacity information to be returned, and a value of NONE prevents that information from being returned. No other value is valid |
--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally |
--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 |
