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.
