Bases: airflow.sensors.base.BaseSensorOperator

Checks for the existence of a file in Google Cloud Storage.

  • folder_id (str) -- The Google drive folder where the file is.

  • file_name (str) -- The name of the file to check in Google Drive

  • drive_id (Optional[str]) -- Optional. The id of the shared Google Drive in which the file resides.

  • gcp_conn_id (str) -- The connection ID to use when connecting to Google Cloud Storage.

  • delegate_to (Optional[str]) -- The account to impersonate using domain-wide delegation of authority, if any. For this to work, the service account making the request must have domain-wide delegation enabled.

  • impersonation_chain (Optional[Union[str, Sequence[str]]]) -- 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 (templated).
