-- Deletes a delivery stream and its data.
--
-- You can delete a delivery stream only if it is in 'ACTIVE' or 'DELETING'
-- state, and not in the 'CREATING' state. While the deletion request is in
-- process, the delivery stream is in the 'DELETING' state.
--
-- To check the state of a delivery stream, use DescribeDeliveryStream.
--
-- While the delivery stream is 'DELETING' state, the service may continue
-- to accept the records, but the service doesn\'t make any guarantees with
-- respect to delivering the data. Therefore, as a best practice, you
-- should first stop any applications that are sending records before
-- deleting a delivery stream.
