Examples of com.amazonaws.services.dynamodbv2.model.GetItemRequest

com.amazonaws.services.dynamodbv2.model.GetItemRequest
Container for the parameters to the {@link com.amazonaws.services.dynamodbv2.AmazonDynamoDB#getItem(GetItemRequest) 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.
@see com.amazonaws.services.dynamodbv2.AmazonDynamoDB#getItem(GetItemRequest)
