-     * Compares the records already known by the client for the given job's result set id with the records that the
-     * dataset directory service knows and if there are any newly discovered records returns a whole array with the
-     * new records filled in.
-     * This method has a very convoluted logic. Here is the explanation of how it works.
-     * If the ordering constraint has to be enforced, the method obtains the first null record in the known records in
-     * the order of the partitions. It always traverses the array in the first to last order!
-     * If known records array or the first element in that array is null in the but the record for that partition now
-     * known to the directory service, the method fills in that record in the array and returns the array back.
-     * However, if the first known null record is not a first element in the array, by induction, all the previous
-     * known records should be known already be known to client and none of the records for the partitions ahead is
-     * known by the client yet. So, we check if the client has reached the end of stream for the partition corresponding
-     * to the record before the first known null record, i.e. the last known non-null record. If not, we just return
-     * null because we cannot expose any new locations until the client reaches end of stream for the last known record.
