<p> Deletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted. </p> <note> If <code>DeleteAttributes</code> is called without being passed any attributes or values specified, all the attributes for the item are deleted. </note> <p> <code>DeleteAttributes</code> is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response. </p> <p> Because Amazon SimpleDB makes multiple copies of item data and uses an eventual consistency update model, performing a <a>GetAttributes</a> or <a>Select</a> operation (read) immediately after a <code>DeleteAttributes</code> or <a>PutAttributes</a> operation (write) might not return updated item data. </p>
