Class PartialRowsData (2.10.0)

PartialRowsData(read_method, request, retry=<google.api_core.retry.Retry object>)

Convenience wrapper for consuming a ReadRows streaming response.

Parameters

Name	Description
read_method	`client._table_data_client.read_rows` `ReadRows` method.
request	`data_messages_v2_pb2.ReadRowsRequest` The `ReadRowsRequest` message used to create a ReadRowsResponse iterator. If the iterator fails, a new iterator is created, allowing the scan to continue from the point just beyond the last successfully read row, identified by self.last_scanned_row_key. The retry happens inside of the Retry class, using a predicate for the expected exceptions during iteration.
retry	`google.api_core.retry.Retry` (Optional) Retry delay and deadline arguments. To override, the default value `DEFAULT_RETRY_READ_ROWS` can be used and modified with the `google.api_core.retry.Retry.with_delay` method or the `google.api_core.retry.Retry.with_deadline` method.

Returns

Type	Description
str	name of state corresponding to current row / chunk processing.

__iter__()

Consume the ReadRowsResponse s from the stream. Read the rows and yield each to the reader

Parse the response and its chunks into a new/existing row in _rows. Rows are returned in order by row key.

cancel()

Cancels the iterator, closing the stream.

consume_all(max_loops=None)

Consume the streamed responses until there are no more.

Parameter

Name	Description
max_loops	`int` (Optional) Maximum number of times to try to consume an additional `ReadRowsResponse`. You can use this to avoid long wait times.
