Deletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted.

If DeleteAttributes is called without being passed any attributes or values

specified, all the attributes for the item are deleted. DeleteAttributes is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Because Amazon SimpleDB makes multiple copies of item data and uses an

eventual consistency update model, performing a GetAttributes or Select operation (read) immediately after a DeleteAttributes or PutAttributes operation (write) might not return updated item data.
