Elements of the primary table key Possible valuess: `PartitionKey`: Name of the partition key `PartitionType`: Partition typee S: The attributee is a string N: The attributee is a numbumber B: The attributee is of the Binary typey type `PartitionKeyValue`: Value of thehe element
`sortKey`, `sortType`,, and `sortKeyValue`	✳️ These parameterss are required for sortable kkeys. Elements of the primary table key Possible valuess: `SortKey`: Name of the sort key `SortType`: Sort typee S: The attributee is a string N: The attributee is a numbumber B: The attributee is of the Binary typey type `SortKeyValue`: Value of the element

`consistentRead`	DynamoDB uses eventually consistent reads unlesunless otherwise specified. Read ad operations such as `GetItem` and `Query` provide a ConsistentRead parameter. If this parameter is set to `true`, DynamoDB uses strongly consistent reads during operation during operation.

Status values

`1`	The adapterr operation was executed succesccessfully
`0`	The operation was not completed, but no error occurred.
`-1`	The operation fafailed due too a technical error.

Input

The adapter expecctss a preedefined XML structuree as input.

Note:

Primary keys can be specified fod for different objects. If the object matches a table in whwhich oonly partitionKey is is defined, only partitionKey ccan be specified. Otherwise,e, partitionKey and SortKey can be specified can be specified.

<?xml version="1.0" encoding="UTF-8" ?>
<PrimaryKeyValues>
	<PrimaryKey partitionKey="2" SortKey="Carlos" />
	<PrimaryKey partitionKey="5" SortKey="Luis" />
</PrimaryKeyValues>

Output

The adapter retrievesrieves the specific element from the desired table and outputss data in an XML structure.

An Item element including fields for the primary key and the associateassociated v values is creaeated for each element. Within the Item element, therehere is a list of the respectespective attributess.

<?xml version="1.0" encoding="UTF-8" ?>
<Result>
	<Item partitionKey="ID" partitionKeyValue="5" SortKey="Name" SortKeyValue="Luis">
