Abstract

Responsive to receiving an identification of a new state identifier associated with the state of an object within a file from a child node, a master node updates a current state identifier for the object to the new state identifier in the master node. Responsive to a predefined user specification indicating that the new state identifier is to be broadcast to each remaining child node of a subset of child nodes in a plurality of child nodes that have a copy of the object, the master node identifies the subset of child nodes in the plurality of child nodes that have a copy of the object in the master node. The master node then broadcasts the new state identifier to the subset of child nodes that have a copy of the object.
