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

com.amazonaws.services.dynamodb.model.GetItemRequest
Container for the parameters to the {@link com.amazonaws.services.dynamodb.AmazonDynamoDB#getItem(GetItemRequest) GetItem operation}.
Retrieves a set of Attributes for an item that matches the primary key.

The GetItem operation provides an eventually-consistent read by default. If eventually-consistent reads are not acceptable for your application, use ConsistentRead . Although this operation might take longer than a standard read, it always returns the last updated value.
@see com.amazonaws.services.dynamodb.AmazonDynamoDB#getItem(GetItemRequest)
