Enabling segmented source data introspection within dispersed storage network (DSN) memory

A non-transitory computer readable storage medium comprises:

• a first memory element that stores operational instructions that, when executed by a first computing device of a dispersed storage network (DSN), causes the first computing device to:
• obtain data for storage in a dispersed storage network (DSN);
• a second memory element that stores operational instructions that, when executed by the first computing device, causes the first computing device to:
• determine whether to divide the data into a plurality of independent data units;
• and
• when determined to divide the data:
• divide the data into the plurality of independent data units;
• generate an aggregation indicator that links the plurality of independent data units to the data;
• and
• send DSN write processing requests and the aggregation indicator to DS processing units of the DSN regarding at least some of the plurality of independent data units;
• a third memory element that stores operational instructions that, when executed by a first dispersed storage (DS) processing unit of the DS processing units, causes the first DS processing unit to:
• receive a first DSN write processing request of the DSN write processing requests and the aggregation indicator, wherein the first DSN write processing request is regarding a first independent data unit of the plurality of independent data units;
• dispersed storage error encode the first independent data unit to produce a first plurality of sets of encoded data slices;
• generate aggregation information regarding the plurality of independent data units based on the aggregation indicator, wherein the first DS processing unit utilizes the aggregation information to process a retrieval request regarding the data or the first independent data unit;
• send the first plurality of sets of encoded data slices to a first set of storage units of the DSN for storage therein;
• a fourth memory element that stores operational instructions that, when executed by the first DS processing unit, causes the first DS processing unit to:
• determine whether the first plurality of sets of encoded data slices have been successfully stored in the first set of storage units;
• when the first plurality of sets of encoded data slices have not been successfully stored, generate an indication to reflect that the first independent data unit is a non-addressable data unit;
• and
• when the first plurality of sets of encoded data slices have been successfully stored, generate the indication to reflect that the first independent data unit is an addressable unit.
