Class ReservationServiceClient (0.1.0)

ReservationServiceClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.bigquery.reservation_v1.services.reservation_service.transports.base.ReservationServiceTransport] = None, client_options: <module 'google.api_core.client_options' from '/workspace/python-bigquery-reservation/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None)

This API allows users to manage their flat-rate BigQuery reservations.

A reservation provides computational resource guarantees, in the form of slots <https://cloud.google.com/bigquery/docs/slots>__, to users. A slot is a unit of computational power in BigQuery, and serves as the basic unit of parallelism. In a scan of a multi-partitioned table, a single slot operates on a single partition of the table. A reservation resource exists as a child resource of the admin project and location, e.g.: projects/myproject/locations/US/reservations/reservationName.

A capacity commitment is a way to purchase compute capacity for BigQuery jobs (in the form of slots) with some committed period of usage. A capacity commitment resource exists as a child resource of the admin project and location, e.g.: projects/myproject/locations/US/capacityCommitments/id.

Methods

ReservationServiceClient

ReservationServiceClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.bigquery.reservation_v1.services.reservation_service.transports.base.ReservationServiceTransport] = None, client_options: <module 'google.api_core.client_options' from '/workspace/python-bigquery-reservation/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None)

Instantiate the reservation service client.

Parameters

Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, .ReservationServiceTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`ClientOptions` Custom options for the client. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. (2) If `transport` argument is None, `client_options` can be used to create a mutual TLS transport. If `client_cert_source` is provided, mutual TLS transport will be created with the given `api_endpoint` or the default mTLS endpoint, and the client SSL credentials obtained from `client_cert_source`.

Exceptions

Type	Description
`google.auth.exceptions.MutualTlsChannelError`	If mutual TLS transport creation failed for any reason.

assignment_path

assignment_path(project: str, location: str, reservation: str, assignment: str)

Return a fully-qualified assignment string.

bi_reservation_path

bi_reservation_path(project: str, location: str)

Return a fully-qualified bi_reservation string.

capacity_commitment_path

capacity_commitment_path(project: str, location: str, capacity_commitment: str)

Return a fully-qualified capacity_commitment string.

create_assignment

create_assignment(request: Optional[google.cloud.bigquery.reservation_v1.types.reservation.CreateAssignmentRequest] = None, *, parent: Optional[str] = None, assignment: Optional[google.cloud.bigquery.reservation_v1.types.reservation.Assignment] = None, retry: google.api_core.retry.Retry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Creates an assignment object which allows the given project to submit jobs of a certain type using slots from the specified reservation.

Currently a resource (project, folder, organization) can only have one assignment per each (job_type, location) combination, and that reservation will be used for all jobs of the matching type.

Different assignments can be created on different levels of the projects, folders or organization hierarchy. During query execution, the assignment is looked up at the project, folder and organization levels in that order. The first assignment found is applied to the query.

When creating assignments, it does not matter if other assignments exist at higher levels.

Example:

The organization organizationA contains two projects, project1 and project2.
Assignments for all three entities (organizationA, project1, and project2) could all be created and mapped to the same or different reservations.

Returns google.rpc.Code.PERMISSION_DENIED if user does not have 'bigquery.admin' permissions on the project using the reservation and the project that owns this reservation.

Returns google.rpc.Code.INVALID_ARGUMENT when location of the assignment does not match location of the reservation.

Looks up assignments for a specified resource for a particular region. If the request is about a project:

Assignments created on the project will be returned if they exist.

permission on the assignee will be verified in this API.
Hierarchy lookup (project->folder->organization) happens in this API.
Parent here is projects/*/locations/*, instead of projects/*/locations/*reservations/*.
