com.amazonaws.services.dynamodbv2.model.UpdateItemRequest
Container for the parameters to the {@link com.amazonaws.services.dynamodbv2.AmazonDynamoDB#updateItem(UpdateItemRequest) UpdateItem operation}.
Edits an existing item's attributes, or inserts a new item if it does not already exist. You can put, delete, or add attribute values. You can also perform a conditional update (insert a new attribute name-value pair if it doesn't exist, or replace an existing name-value pair if it has certain expected attribute values).

In addition to updating an item, you can also return the item's attribute values in the same operation, using the ReturnValues parameter.
