Abstract:
A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory. The processing circuitry is configured to execute the operational instructions to perform various operations and functions. The computing device operates based on a store data request from a requesting entity to dispersed error encode a data segment associated with a data object to generate a set of encoded data slices (EDSs). The computing device selects a write threshold number of EDSs based on a desired consistency level indicator and issues a write request to storage unit(s) (SU(s)). The computing device receives write response(s) from the SU(s) and, based on write response(s) received from the at least some of the SU(s), provides a store data response to the requesting entity.
