> include_row_kind=False,
> row_kind_field="__row_kind__",
> ) -> CloseableIterator[Dict[str, Any]]

> batch_size=1000,
> batch_format="pandas",
> include_row_kind=False,
> row_kind_field="__row_kind__",
> ) -> CloseableIterator {code}
> Also add bounded retrieval helpers:
> {code:java}
> def take(self, n, *, timeout=None, include_row_kind=False, ...) -> List[Dict]
