Description
The API describes a startIndex parameter for the "Tabledata: list" endpoint. But the implementation doesn't include this parameter. An example of a class does implement a startIndex parameter is bigquery.query.Query as described in the "Jobs: getQueryResults" endpoint.
I tried editing the code to submit a PR, but I'm not familiar with testing this kind of Python package locally (pip install -e . didn't install the packages from their local copy as I expected). In lieu of a PR I can share this patched class TableWithStartIndex that works for my use case:
from google.cloud.bigquery.table import Table, _item_to_row, _rows_page_start
from google.cloud.iterator import HTTPIterator
class TableWithStartIndex(Table):
def fetch_data_with_start_index(self, max_results=None, page_token=None, client=None, start_index=None):
client = self._require_client(client)
path = '%s/data' % (self.path,)
extra_params = {}
if start_index is not None:
extra_params['startIndex'] = start_index
iterator = HTTPIterator(client=client, path=path,
item_to_value=_item_to_row, items_key='rows',
page_token=page_token, max_results=max_results,
page_start=_rows_page_start,
extra_params=extra_params)
iterator.schema = self._schema
# Over-ride the key used to retrieve the next page token.
iterator._NEXT_TOKEN = 'pageToken'
return iteratorI added three small chunks: the start_index=None argument, this block:
extra_params = {}
if start_index is not None:
extra_params['startIndex'] = start_indexAnd the bit that passes the extra_params to the HTTPIterator: extra_params=extra_params.
