    """
    Performs checks against BigQuery. The ``BigQueryCheckOperator`` expects
    a sql query that will return a single row. Each value on that
    first row is evaluated using python ``bool`` casting. If any of the
    values return ``False`` the check is failed and errors out.

    .. seealso::
        For more information on how to use this operator, take a look at the guide:
        :ref:`howto/operator:BigQueryCheckOperator`

    Note that Python bool casting evals the following as ``False``:

    * ``False``
    * ``0``
    * Empty string (``""``)
    * Empty list (``[]``)
    * Empty dictionary or set (``{}``)

    Given a query like ``SELECT COUNT(*) FROM foo``, it will fail only if
    the count ``== 0``. You can craft much more complex query that could,
    for instance, check that the table has the same number of rows as
    the source table upstream, or that the count of today's partition is
    greater than yesterday's partition, or that a set of metrics are less
    than 3 standard deviation for the 7 day average.

    This operator can be used as a data quality check in your pipeline, and
    depending on where you put it in your DAG, you have the choice to
    stop the critical path, preventing from
    publishing dubious data, or on the side and receive email alerts
    without stopping the progress of the DAG.

        of the basic price.
        Defaults to None, in which case it uses the value set in the project.
    :param maximum_bytes_billed: Limits the bytes billed for this job.
        Queries that will have bytes billed beyond this limit will fail
        (without incurring a charge). If unspecified, this will be
        set to your project default.
    :param api_resource_configs: a dictionary that contain params
        'configuration' applied for Google BigQuery Jobs API:
        https://cloud.google.com/bigquery/docs/reference/rest/v2/jobs
        for example, {'query': {'useQueryCache': False}}. You could use it
        if you need to provide some params that are not supported by BigQueryOperator
        like args.
    :param schema_update_options: Allows the schema of the destination
        table to be updated as a side effect of the load job.
    :param query_params: a list of dictionary containing query parameter types and
        values, passed to BigQuery. The structure of dictionary should look like
        'queryParameters' in Google BigQuery Jobs API:
        https://cloud.google.com/bigquery/docs/reference/rest/v2/jobs.
        For example, [{ 'name': 'corpus', 'parameterType': { 'type': 'STRING' },
        'parameterValue': { 'value': 'romeoandjuliet' } }]. (templated)
    :param labels: a dictionary containing labels for the job/query,
        passed to BigQuery
    :param priority: Specifies a priority for the query.
        Possible values include INTERACTIVE and BATCH.
        The default value is INTERACTIVE.
    :param time_partitioning: configure optional time partitioning fields i.e.
        partition by field, type and expiration as per API specifications.
    :param cluster_fields: Request that the result of this query be stored sorted
        by one or more columns. BigQuery supports clustering for both partitioned and
        non-partitioned tables. The order of columns given determines the sort order.
    :param location: The geographic location of the job. Required except for
        US and EU. See details at
        https://cloud.google.com/bigquery/docs/locations#specifying_your_location
    :param encryption_configuration: [Optional] Custom encryption configuration (e.g., Cloud KMS keys).
        **Example**: ::

            encryption_configuration = {
                "kmsKeyName": "projects/testp/locations/us/keyRings/test-kr/cryptoKeys/test-key"
            }
    :param impersonation_chain: 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).

    Creates a new, empty table in the specified BigQuery dataset,
    optionally with schema.

    The schema to be used for the BigQuery table may be specified in one of
    two ways. You may either directly pass the schema fields in, or you may
    point the operator to a Google Cloud Storage object name. The object in
    Google Cloud Storage must be a JSON file with the schema fields in it.
    You can also create a table without schema.

        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).
    :param if_exists: What should Airflow do if the table exists. If set to `log`, the TI will be passed to
        success and an error message will be logged. Set to `ignore` to ignore the error, set to `fail` to
        fail the TI, and set to `skip` to skip it.

class BigQueryCreateExternalTableOperator(GoogleCloudBaseOperator):
    """
    Creates a new external table in the dataset with the data from Google Cloud
    Storage.

    The schema to be used for the BigQuery table may be specified in one of
    two ways. You may either directly pass the schema fields in, or you may
    point the operator to a Google Cloud Storage object name. The object in
    Google Cloud Storage must be a JSON file with the schema fields in it.

    .. seealso::
        For more information on how to use this operator, take a look at the guide:
        :ref:`howto/operator:BigQueryCreateExternalTableOperator`

    :param bucket: The bucket to point the external table to. (templated)
    :param source_objects: List of Google Cloud Storage URIs to point
        table to. If source_format is 'DATASTORE_BACKUP', the list must only contain a single URI.
    :param destination_project_dataset_table: The dotted ``(<project>.)<dataset>.<table>``
        BigQuery table to load data into (templated). If ``<project>`` is not included,
        project will be the project defined in the connection json.
    :param schema_fields: If set, the schema field list as defined here:
        https://cloud.google.com/bigquery/docs/reference/rest/v2/jobs#configuration.load.schema

        **Example**: ::

            schema_fields=[{"name": "emp_name", "type": "STRING", "mode": "REQUIRED"},
                           {"name": "salary", "type": "INTEGER", "mode": "NULLABLE"}]

        Should not be set when source_format is 'DATASTORE_BACKUP'.
    :param table_resource: Table resource as described in documentation:
        https://cloud.google.com/bigquery/docs/reference/rest/v2/tables#Table
        If provided all other parameters are ignored. External schema from object will be resolved.
    :param schema_object: If set, a GCS object path pointing to a .json file that
        contains the schema for the table. (templated)
    :param gcs_schema_bucket: GCS bucket name where the schema JSON is stored (templated).
        The default value is self.bucket.
    :param source_format: File format of the data.
    :param autodetect: Try to detect schema and format options automatically.
        The schema_fields and schema_object options will be honored when specified explicitly.
        https://cloud.google.com/bigquery/docs/schema-detect#schema_auto-detection_for_external_data_sources
    :param compression: [Optional] The compression type of the data source.
        Possible values include GZIP and NONE.
        The default value is NONE.
        This setting is ignored for Google Cloud Bigtable,
        Google Cloud Datastore backups and Avro formats.
    :param skip_leading_rows: Number of rows to skip when loading from a CSV.
    :param field_delimiter: The delimiter to use for the CSV.
    :param max_bad_records: The maximum number of bad records that BigQuery can
        ignore when running the job.
    :param quote_character: The value that is used to quote data sections in a CSV file.
    :param allow_quoted_newlines: Whether to allow quoted newlines (true) or not (false).
    :param allow_jagged_rows: Accept rows that are missing trailing optional columns.
        The missing values are treated as nulls. If false, records with missing trailing
        columns are treated as bad records, and if there are too many bad records, an
        invalid error is returned in the job result. Only applicable to CSV, ignored
        for other formats.
    :param gcp_conn_id: (Optional) The connection ID used to connect to Google Cloud and
        interact with the Bigquery service.
    :param google_cloud_storage_conn_id: (Optional) The connection ID used to connect to Google Cloud
        and interact with the Google Cloud Storage service.
    :param src_fmt_configs: configure optional fields specific to the source format
    :param labels: a dictionary containing labels for the table, passed to BigQuery
    :param encryption_configuration: [Optional] Custom encryption configuration (e.g., Cloud KMS keys).
        **Example**: ::

            encryption_configuration = {
                "kmsKeyName": "projects/testp/locations/us/keyRings/test-kr/cryptoKeys/test-key"
            }
    :param location: The location used for the operation.
    :param impersonation_chain: 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).

    Executes a BigQuery job. Waits for the job to complete and returns job id.
    This operator work in the following way:

    - it calculates a unique hash of the job using job's configuration or uuid if ``force_rerun`` is True
    - creates ``job_id`` in form of
        ``[provided_job_id | airflow_{dag_id}_{task_id}_{exec_date}]_{uniqueness_suffix}``
    - submits a BigQuery job using the ``job_id``
    - if job with given id already exists then it tries to reattach to the job if its not done and its
        state is in ``reattach_states``. If the job is done the operator will raise ``AirflowException``.

    Using ``force_rerun`` will submit a new job every time without attaching to already existing ones.

    :param job_id: The ID of the job. It will be suffixed with hash of job configuration
        unless ``force_rerun`` is True.
        The ID must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), or
        dashes (-). The maximum length is 1,024 characters. If not provided then uuid will
        be generated.
    :param force_rerun: If True then operator will use hash of uuid as job id suffix
    :param reattach_states: Set of BigQuery job's states in case of which we should reattach
        to the job. Should be other than final states.
    :param project_id: Google Cloud Project where the job is running
