ReturnValue enum

Use this parameter if you want to get the attribute name-value pairs before or after they are modified. For PUT operations, the possible parameter values are NONE (default) or ALL_OLD. For update operations, the possible parameter values are NONE (default) or ALL_OLD, UPDATED_OLD, ALL_NEW or UPDATED_NEW.

• NONE: Nothing is returned.
• ALL_OLD: Returns the attributes of the item as they were before the operation.
• UPDATED_OLD: Returns the values of the updated attributes, only, as they were before the operation.
• ALL_NEW: Returns all the attributes and their new values after the operation.
• UPDATED_NEW: Returns the values of the updated attributes, only, as they are after the operation.
