C# Class Amazon.DynamoDBv2.Model.GetItemRequest

Container for the parameters to the GetItem operation. The GetItem operation returns a set of attributes for the item with the given primary key. If there is no matching item, GetItem does not return any data.

GetItem provides an eventually consistent read by default. If your application requires a strongly consistent read, set ConsistentRead to true. Although a strongly consistent read might take more time than an eventually consistent read, it always returns the last updated value.

GetItemRequest() public méthode

Instantiates GetItemRequest with the parameterized properties

public GetItemRequest ( string tableName, AttributeValue>.Dictionary key ) : System
tableName	string	The name of the table containing the requested item.
key	AttributeValue>.Dictionary	A map of attribute names to AttributeValue objects, representing the primary key of the item to retrieve. For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

consistentRead	bool	Determines the read consistency model: If set to `true`, then the operation uses strongly consistent reads; otherwise, the operation uses eventually consistent reads.
