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

--
-- -   @NONE@ - If @ReturnValues@ is not specified, or if its value is
--     @NONE@, then nothing is returned. (This setting is the default for
--     @ReturnValues@.)
--
-- -   @ALL_OLD@ - The content of the old item is returned.

-- The @ReturnValues@ parameter is used by several DynamoDB operations;
-- however, @DeleteItem@ does not recognize any values other than @NONE@ or

-- | Information about item collections, if any, that were affected by the
-- @DeleteItem@ operation. @ItemCollectionMetrics@ is only returned if the
-- @ReturnItemCollectionMetrics@ parameter was specified. If the table does
-- not have any local secondary indexes, this information is not returned
-- in the response.
--
-- Each @ItemCollectionMetrics@ element consists of:
--
-- -   @ItemCollectionKey@ - The partition key value of the item
--     collection. This is the same as the partition key value of the item
--     itself.
--
-- -   @SizeEstimateRangeGB@ - An estimate of item collection size, in
--     gigabytes. This value is a two-element array containing a lower
--     bound and an upper bound for the estimate. The estimate includes the
--     size of all the items in the table, plus the size of all attributes
--     projected into all of the local secondary indexes on that table. Use
--     this estimate to measure whether a local secondary index is
--     approaching its size limit.
--
--     The estimate is subject to change over time; therefore, do not rely
--     on the precision or accuracy of the estimate.
