Methods

add_done_callback

add_done_callback(fn)

Add a callback to be executed when the operation is complete.

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

Parameter
Name	Description
`fn`	`Callable[Future]` The callback to execute when the operation is complete.

cancel

cancel(client=None,retry:typing.Optional[google.api_core.retry.retry_unary.Retry]=google.api_core.retry.retry_unary.Retry,timeout:typing.Optional[float]=None,)->bool

API call: cancel job via a POST request

Seehttps://cloud.google.com/bigquery/docs/reference/rest/v2/jobs/cancel

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`

Returns
Type	Description
`bool`	Boolean indicating that the cancel request was sent.

cancelled

cancelled()

Check if the job has been cancelled.

This always returns False. It's not possible to check if a job wascancelled in the API. This method is here to satisfy the interfaceforgoogle.api_core.future.Future.

Returns
Type	Description
`bool`	False

done

done(retry:google.api_core.retry.retry_unary.Retry=google.api_core.retry.retry_unary.Retry,timeout:typing.Optional[float]=128,reload:bool=True,)->bool

Checks if the job is complete.

Parameters
Name	Description
`timeout`	`Optional[float]` The number of seconds to wait for the underlying HTTP transport before using`retry`.
`reload`	`Optional[bool]` If`True`, make an API call to refresh the job state of unfinished jobs before checking. Default`True`.
`retry`	`Optional[google.api_core.retry.Retry]` How to retry the RPC. If the job state is`DONE`, retrying is aborted early, as the job will not change anymore.

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

exception

exception(timeout=object)

Get the exception from the operation, blocking if necessary.

See the documentation for theresult method for details on howthis method operates, as bothresult and this method rely on theexact same polling logic. The only difference is that this method doesnot acceptretry andpolling arguments but relies on the default onesinstead.

Parameter
Name	Description
`timeout`	`int` How long to wait for the operation to complete.

Returns
Type	Description
`Optional[google.api_core.GoogleAPICallError]`	The operation's error.

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

Parameters
Name	Description
`timeout`	`Optional[float]` The number of seconds to wait for the underlying HTTP transport before using`retry`.

Type	Description
`bool`	Boolean indicating existence of the job.

from_api_repr

from_api_repr(resource:dict,client)->google.cloud.bigquery.job.base.UnknownJob
