The basic example iterated a Table, which is not iterable; it now reads batches through an identity Permutation. The two-phase shuffle passed block_size, window_blocks and max_shuffle_distance, which StreamingDataset does not accept: its block-wise option is shuffle_clump_size, which shuffles contiguous groups of rows as units. That section, the shuffling introduction and the split explanation now describe that, under the old anchors, and the fetching example uses io_queue_depth in place of the deprecated prefetch_batches. Each changed example was run locally against the baseline SDK.
