NOTHING RETRIES FOR YOU. With no integration layer there is no orchestrator holding state, so the retry, the dead letter and the alert have to live somewhere you chose deliberately. THE RETRY. For an inbound file, the retry is the file still sitting in the inbound folder — which is why Lesson 2 moves files rather than deleting them: an unmoved file is a retry queue that costs nothing.
