Archive and replay
This revision card explains Archive and replay. A bug in a consumer drops a day of order events; you need those events again. It describes archive stores events from a bus; replay sends them again to selected rules. The how-to section covers how to enable archive on the bus with a retention period; after a fix, start a replay for the failed window. An example on the card is replay metrics show events re-delivered; ship Lambda processes the missed OrderPlaced set.
