Module row_data (1.4.0)

Container for Google Cloud Bigtable Cells and Streaming Row Contents.

Classes

Cell(value, timestamp_micros, labels=None)

Representation of a Google Cloud Bigtable Cell.

Parameters

Name	Description
`value`	`bytes` The value stored in the cell.
`timestamp_micros`	`int` The timestamp_micros when the cell was stored.
`labels`	`list` (Optional) List of strings. Labels applied to the cell.

Exception raised to to invalid chunk data from back-end.

Exception raised to to invalid response data from back-end.

PartialCellData(
    row_key, family_name, qualifier, timestamp_micros, labels=(), value=b""
)

Representation of partial cell in a Google Cloud Bigtable Table.

These are expected to be updated directly from a ._generated.bigtable_service_messages_pb2.ReadRowsResponse

Parameters

Name	Description
`row_key`	`bytes` The key for the row holding the (partial) cell.
`family_name`	`str` The family name of the (partial) cell.
`qualifier`	`bytes` The column qualifier of the (partial) cell.
`timestamp_micros`	`int` The timestamp (in microsecods) of the (partial) cell.
`labels`	`list of str` labels assigned to the (partial) cell
`value`	`bytes` The (accumulated) value of the (partial) cell.

PartialRowData(row_key)

Representation of partial row in a Google Cloud Bigtable Table.

These are expected to be updated directly from a ._generated.bigtable_service_messages_pb2.ReadRowsResponse

Parameter

Name	Description
`row_key`	`bytes` The key for the row holding the (partial) data.

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.
