/**
* <p>Deletes a single item in a table by primary key. You can perform a conditional delete
* operation that deletes the item if it exists, or if it has an expected attribute
* value.</p>
* <p>In addition to deleting an item, you can also return the item's attribute values in
* the same operation, using the <code>ReturnValues</code> parameter.</p>
* <p>Unless you specify conditions, the <code>DeleteItem</code> is an idempotent operation;
* running it multiple times on the same item or attribute does <i>not</i>
* result in an error response.</p>
* <p>Conditional deletes are useful for deleting items only if specific conditions are met.
* If those conditions are met, DynamoDB performs the delete. Otherwise, the item is not
* deleted.</p>
* @example
* Use a bare-bones client and the command you need to make an API call.
