Abstract:
1. A method for a system including a plurality of nodes which store a content data by associating with a metadata object, the method comprising the steps of: generating a map that identifies a node that stores an authoritative copy of a region for the metadata object, and zero or more nodes that store zero or more backup copies of the region for the metadata object, the number of the backup copies being determined based on a metadata tolerable points of failure (TPOF) configuration parameter; distributing the map across the plurality of nodes so that each node can identify a location of the authoritative copy or backup copy; after a state of the authoritative copy or the backup copy is changed, updating the map to reflect the change of the state; distributing the updated map across the plurality of nodes; and processing an access to the metadata object on each node of the plurality of nodes by referring to the distributed map.
