Abstract
A method includes determining a desired retrieval resolution of a data segment. A first sub-set of encoded data slices corresponds to a first resolution of the data segment, a second sub-set of encoded data slices corresponds to a second resolution, and a third sub-set of encoded data slices corresponds to redundancy encoded data slices. The method further includes, when the desired retrieval resolution is the first resolution, sending first requests to storage units regarding the first sub-set of encoded data slices, and dispersed storage error decoding the first sub-set of encoded data slices to recover the data segment at the first resolution. The method further includes, when the desired retrieval resolution is the second resolution, sending second requests to storage units regarding the second sub-set of encoded data slices, and dispersed storage error decoding the second sub-set of encoded data slices to recover the data segment at the second resolution.
