__init__(job_id, sources, destination, client, job_config=None)

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

add_done_callback

If the operation is not already complete, this will start a helper thread to poll for the status of the operation in the background.

Parameters

Name	Description
client	`Optional[google.cloud.bigquery.client.Client]` the client to use. If not passed, falls back to the `client` stored on the current dataset.
retry	`Optional[google.api_core.retry.Retry]` How to retry the RPC.
timeout	`Optional[float]` The number of seconds to wait for the underlying HTTP transport before using `retry`

Refresh the job and checks if it is complete.

Parameters

Type	Description
bool	True if the job is complete, False otherwise.

exception

API call: test for the existence of the job via a GET request

See https://cloud.google.com/bigquery/docs/reference/rest/v2/jobs/get

Parameters

Name	Description
client	`Optional[google.cloud.bigquery.client.Client]` the client to use. If not passed, falls back to the `client` stored on the current dataset.
retry	`google.api_core.retry.Retry` (Optional) How to retry the RPC.
