More Information
Summary:A healing procedure is disclosed for distributed database. A storage node locally stores metadata for a plurality of data items stored in the distributed database. The metadata includes, for each data item, an identifier associated with the data item and an associated replica location list indicating one or more storage nodes in the distributed database storing replicas of the data item. Responsive to a trigger indicating a fault in a second storage node, the storage node iterates over the metadata to identify compromised data items for which the first storage node is designated as a healing node and performs a healing procedure for each compromised data item where the first storage node is designated as the healing node.
