DeleteItem Method (deleteItemRequest)
AmazonAmazon.DynamoDBv2AmazonDynamoDBDeleteItem(DeleteItemRequest) Did this page help you?   Yes   No    Tell us about it...

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.

In addition to deleting an item, you can also return the item's attribute values in the same operation, using the ReturnValues parameter.

Unless you specify conditions, the DeleteItem is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Conditional deletes are useful for only deleting items if specific conditions are met. If those conditions are met, DynamoDB performs the delete. Otherwise, the item is not deleted.
