Abstract
Database recovery of independently replicated shards may be performed. A recovery event to make a mirror location of shards of a database that is replicated independently and asynchronously from a primary location of the database is detected. To make the mirror location a new read-write location of the database according to the detected recovery event, a recovery point may be identified based on a gossip protocol that shares progress across the different shards in the mirror location that is used to access the database as the new read-write location.
