Abstract

See full text

A method begins by a dispersed storage (DS) processing module traversing multiple index structures based on search criteria to identify an object retrieval structure. The method continues with the DS processing module retrieving a set of encoded data slices corresponding to the object retrieval structure from a dispersed storage network (DSN) and decoding the set of encoded data slices in accordance with a dispersed storage error coding function to recover the object retrieval structure. The method continues with the DS processing module identifying one of one or more data version records of the recovered object retrieval structure based on the search criteria to produce an identified data version record and determining DSN addressing information for at least a portion of data based on information of the identified data version record.
