Starts a new asynchronous job. This API has two different kinds of endpoint URIs, as this method supports a variety of use cases. * The Metadata URI is used for most interactions, as it accepts the job configuration directly. * The Upload URI is ONLY for the case when you're sending both a load job configuration and a data stream together. In this case, the Upload URI accepts the job configuration and the data as two distinct multipart MIME parts. # IAM Permissions Requires the bigquery.jobs.create permission on the project resource. Additional permissions are required depending on the job type: - Load, Export, and Copy jobs: Generally require data-level permissions such as bigquery.tables.export or access to external storage. - Query jobs: Permissions are dependent on the SQL statement. Complex queries (DDL, DCL) may require additional permissions to create reservations, modify IAM policies, or update project settings.
