Abstract
A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method begins by, receiving a write data object request and writing and committing the data object as a set of encoded data slices into DSN memory. The method continues by writing and committing an index consistency write-intent to DSN memory. The method continues by writing metadata of the data object to DSN memory. The method continues by write and committing an index entry to DSN memory. The method continues, during a finalization of the index consistency write-intent, by executing the index consistency write-intent to ensure consistency between the metadata of the data object and metadata located in the index entry.
