Personally I think using BatchMapTransformFn with disabled_shaping is easier to understand than OutputBlockSizeOption.target_num_rows_per_block
| 2. Whenever the pending total reaches the target row count, try to build a ready bundle. | ||
| 3. Determine the slice needed from the final bundle so the ready bundle holds an exact multiple of the target rows. | ||
| 4. Submit that ready bundle to a remote map task; the task slices each block according to the slice metadata stored in the RefBundle (the bundle now contains n × target rows for n ≥ 1). | ||
| 5. We configured the `OutputBlockSizeOption.target_num_rows_per_block` to the target number of rows per block in plan_streaming_repartition_op so the output buffer further splits the n × target rows into n blocks of exactly the target size. |

Let's also add comments to MAX_SAFE_ROWS_PER_BLOCK_FACTOR saying it should be < 2
