Users can determine the precise origins of their data by collecting detailed provenance records. However, auditing at a finer grain produces large amounts of metadata. To efficiently manage the collected provenance, several provenance management systems, including SPADE, record provenance on the hosts where it is generated. Distributed provenance raises the issue of efficient reconstruction during the query phase. Recursively querying provenance metadata or computing its transitive closure is known to have limited scalability and cannot be used for large provenance graphs.
