class airflow.providers.google.cloud.triggers.bigquery.BigQueryInsertJobTrigger(conn_id, job_id, project_id, dataset_id=None, table_id=None, poll_interval=4.0, impersonation_chain=None)[source]

Bases: airflow.triggers.base.BaseTrigger

BigQueryInsertJobTrigger run on the trigger worker to perform insert operation.

Parameters

  • conn_id (str) – Reference to google cloud connection id

  • job_id (str | None) – The ID of the job. It will be suffixed with hash of job configuration

  • project_id (str | None) – Google Cloud Project where the job is running

  • dataset_id (str | None) – The dataset ID of the requested table. (templated)

  • table_id (str | None) – The table ID of the requested table. (templated)

  • poll_interval (float) – polling period in seconds to check for the status. (templated)

  • impersonation_chain (str | Sequence[str] | None) – Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account.
