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 and there will be no
Item element in the response.
GetItem provides an eventually consistent read by default. If your application
requires a strongly consistent read, set
Although a strongly consistent read might take more time than an eventually consistent
read, it always returns the last updated value.
For PCL and Unity this operation is only available in asynchronous form. Please refer to GetItemAsync.
public virtual GetItemResponse GetItem( String tableName, Dictionary<String, AttributeValue> key, Boolean consistentRead )
The name of the table containing the requested item.
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.
Determines the read consistency model: If set to true, then the operation uses strongly consistent reads; otherwise, the operation uses eventually consistent reads.
