Determining event causality including employment of partitioned event space

Causal relationships between events in a plurality of interrelated causal chains are maintained in a network event space through the partitioning of the event space into event subspaces. In this manner, events sharing the same event subspace stay constant so long as the partitioned subspace is substantially causally consistent. The causality of events from different neighboring subspaces may be determined through the individual subspace determination on each query event until a joining of shared boundary events is possible.
