Data access in a dispersed storage network with consistency

Abstract:

A method is presented for execution by a processing system of a dispersed storage and task (DST) processing unit that includes a processor. The method includes: receiving, at the processor, a data access request having a consistency indicator; identifying, via the processor, a set of two or more storage targets associated with the data access request; selecting, via the processor, a threshold number of storage targets of the set of two or more storage targets, based on the consistency indicator; accessing, via the processor, the selected threshold number of storage targets based on the data access request; and generating a data access response, via the processor, based on the accessing of the selected threshold number of storage targets.
