Abstract
A method includes determining that a primary delegate device is unavailable. The method continues by identifying a fallback delegate device for changing a node of a hierarchical index structure using a deterministic function. The deterministic function includes performing a first modification of global namespace address of the unavailable primary delegate device to produce a first modified address identifier. The deterministic function further includes determining whether another delegate device of the plurality of delegate devices has a global namespace address corresponding to the first modified address identifier. When the global namespace address of other delegate device corresponds to the first modified address identifier, the method further includes processing a change to a node of the one or more nodes via the other delegate device as the fallback delegate device.
