The attributes to be returned in the result. You can retrieve all item attributes, specific item attributes, or the count of matching items.
- ALL_ATTRIBUTES: Returns all of the item attributes.
- COUNT: Returns the number of matching items, rather than the matching items themselves.
- SPECIFIC_ATTRIBUTES : Returns only the attributes listed in AttributesToGet. This is equivalent to specifying AttributesToGet without specifying any value for Select.
