google.cloud.bigquery.job.ExtractJobConfig

class google.cloud.bigquery.job.ExtractJobConfig(**kwargs)

Configuration options for extract jobs.

All properties in this class are optional. Values which are None -> server defaults. Set properties on the constructed configuration by using the property name as the name of a keyword argument.

__init__(**kwargs)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(**kwargs)	Initialize self.
from_api_repr(resource)	Factory: construct a job configuration given its API representation
to_api_repr()	Build an API representation of the job config.

Attributes

compression	Compression type to use for exported files.
destination_format	Exported file format.
field_delimiter	Delimiter to use between fields in the exported data.
labels	Labels for the job.
print_header	Print a header row in the exported data.
use_avro_logical_types	For loads of Avro data, governs whether Avro logical types are converted to their corresponding BigQuery types (e.g.

property compression

Type

str

classmethod from_api_repr(resource)

Factory: construct a job configuration given its API representation

Parameters

resource (Dict) – A job configuration in the same representation as is returned from the API.

Returns

Configuration parsed from resource.

Return type

google.cloud.bigquery.job._JobConfig

property labels

Labels for the job.

This method always returns a dict. To change a job’s labels, modify the dict, then call Client.update_job. To delete a label, set its value to None before updating.

to_api_repr()

Build an API representation of the job config.

Returns

A dictionary in the format used by the BigQuery API.

Return type

Dict

property use_avro_logical_types

For loads of Avro data, governs whether Avro logical types are converted to their corresponding BigQuery types (e.g. TIMESTAMP) rather than raw types (e.g. INTEGER).

Type

bool
