Skip rows with datasets.Dataset.map()

Is there a way to make from a single row multiple rows, i.e. how do I make multiple rows in the new dataset from a row in the old dataset?

You can use a batched map to return as many rows as you want given a batch of rows. See docs

Yes, using a batched map as mentioned earlier
