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.

Properties

state

State machine state.

Returns

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

Methods

__iter__

__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

cancel()

Cancels the iterator, closing the stream.

consume_all

consume_all(max_loops=None)

Consume the streamed responses until there are no more.

Warning: This method will be removed in future releases. Please use this class as a generator instead.

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.
