1. A method for execution by a computing device, the method comprises: obtaining a data object identifier regarding a large data object; obtaining a plurality of boundary indicators that identify partition boundaries between data partitions of a plurality of data partitions of the large data object, wherein one or more retrieval preferences is associated with a boundary indicator of the plurality of boundary indicators; for a data partition of the plurality of data partitions, wherein the data partition is dispersed storage error encoded into one or more sets of encoded data slices: generating one or more sets of dispersed storage network (DSN) addresses for the one or more sets of encoded data slices, wherein each DSN address of the one or more sets of DSN addresses includes a common identifier for the data partition of the large data object, a common indicator of the one or more retrieval preferences, and a unique encoded data slice identifier such that a first DSN address of the one or more sets of DSN addresses for a first encoded data slices of the one or more sets of encoded data slices has the common identifier for the data partition, the common indicator of the one or more retrieval preferences, and a first unique encoded data slice identifier and a second DSN address of the one or more sets of DSN addresses for a second encoded data slices of the one or more sets of encoded data slices has the common identifier for the data partition, the common indicator of the one or more retrieval preferences, and a second unique encoded data slice identifier.
