Interface ReservationServiceGrpc.AsyncService (2.52.0) 

public static interface ReservationServiceGrpc.AsyncService

This API allows users to manage their BigQuery reservations. A reservation provides computational resource guarantees, in the form of 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

createAssignment(CreateAssignmentRequest request, StreamObserver<Assignment> responseObserver)

public default void createAssignment(CreateAssignmentRequest request, StreamObserver<Assignment> responseObserver)

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. "None" assignments represent an absence of the assignment. Projects assigned to None use on-demand pricing. To create a "None" assignment, use "none" as a reservation_id in the parent. Example parent: projects/myproject/locations/US/reservations/none. 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.
Parameters
Name Description
request CreateAssignmentRequest
responseObserver io.grpc.stub.StreamObserver<Assignment>

createCapacityCommitment(CreateCapacityCommitmentRequest request, StreamObserver<CapacityCommitment> responseObserver)

public default void createCapacityCommitment(CreateCapacityCommitmentRequest request, StreamObserver<CapacityCommitment> responseObserver)

Creates a new capacity commitment resource.

Parameters
Name Description
request CreateCapacityCommitmentRequest
responseObserver io.grpc.stub.StreamObserver<CapacityCommitment>

createReservation(CreateReservationRequest request, StreamObserver<Reservation> responseObserver)

public default void createReservation(CreateReservationRequest request, StreamObserver<Reservation> responseObserver)

Creates a new reservation resource.

Parameters
Name Description
request CreateReservationRequest
responseObserver io.grpc.stub.StreamObserver<Reservation>

deleteAssignment(DeleteAssignmentRequest request, StreamObserver<Empty> responseObserver)

public default void deleteAssignment(DeleteAssignmentRequest request, StreamObserver<Empty> responseObserver)

Deletes a assignment. No expansion will happen. Example:

  • Organization organizationA contains two projects, project1 and project2.
  • Reservation res1 exists and was created previously.
  • CreateAssignment was used previously to define the following associations between entities and reservations: <organizationA, res1> and <project1, res1> In this example, deletion of the <organizationA, res1> assignment won't affect the other assignment <project1, res1>. After said deletion, queries from project1 will still use res1 while queries from project2 will switch to use on-demand mode.
Parameters
Name Description
request DeleteAssignmentRequest
responseObserver io.grpc.stub.StreamObserver<Empty>

deleteCapacityCommitment(DeleteCapacityCommitmentRequest request, StreamObserver<Empty> responseObserver)

public default void deleteCapacityCommitment(DeleteCapacityCommitmentRequest request, StreamObserver<Empty> responseObserver)

Deletes a capacity commitment. Attempting to delete capacity commitment before its commitment_end_time will fail with the error code google.rpc.Code.FAILED_PRECONDITION.

Parameters
Name Description
request DeleteCapacityCommitmentRequest
responseObserver io.grpc.stub.StreamObserver<Empty>

deleteReservation(DeleteReservationRequest request, StreamObserver<Empty> responseObserver)

public default void deleteReservation(DeleteReservationRequest request, StreamObserver<Empty> responseObserver)

Deletes a reservation. Returns google.rpc.Code.FAILED_PRECONDITION when reservation has assignments.

Parameters

getCapacityCommitment(GetCapacityCommitmentRequest request, StreamObserver<CapacityCommitment> responseObserver)

public default void getCapacityCommitment(GetCapacityCommitmentRequest request, StreamObserver<CapacityCommitment> responseObserver)

Returns information about the capacity commitment.

Parameters
Name Description

listAssignments(ListAssignmentsRequest request, StreamObserver<ListAssignmentsResponse> responseObserver)

public default void listAssignments(ListAssignmentsRequest request, StreamObserver<ListAssignmentsResponse> responseObserver)

Lists assignments. Only explicitly created assignments will be returned. Example:

  • Organization organizationA contains two projects, project1 and project2.
  • Reservation res1 exists and was created previously.
  • CreateAssignment was used previously to define the following associations between entities and reservations: <organizationA, res1> and <project1, res1> In this example, ListAssignments will just return the above two assignments for reservation res1, and no expansion/merge will happen. The wildcard "-" can be used for reservations in the request. In that case all assignments belongs to the specified project and location will be listed. Note "-" cannot be used for projects nor locations.
Parameters
Name Description
request ListAssignmentsRequest
responseObserver io.grpc.stub.StreamObserver<ListAssignmentsResponse>

listCapacityCommitments(ListCapacityCommitmentsRequest request, StreamObserver<ListCapacityCommitmentsResponse> responseObserver)

mergeCapacityCommitments(MergeCapacityCommitmentsRequest request, StreamObserver<CapacityCommitment> responseObserver)

public default void mergeCapacityCommitments(MergeCapacityCommitmentsRequest request, StreamObserver<CapacityCommitment> responseObserver)

Merges capacity commitments of the same plan into a single commitment. The resulting capacity commitment has the greater commitment_end_time out of the to-be-merged capacity commitments. Attempting to merge capacity commitments of different plan will fail with the error code google.rpc.Code.FAILED_PRECONDITION.

Parameters
Name Description
request MergeCapacityCommitmentsRequest
responseObserver io.grpc.stub.StreamObserver<CapacityCommitment>

moveAssignment(MoveAssignmentRequest request, StreamObserver<Assignment> responseObserver)

public default void moveAssignment(MoveAssignmentRequest request, StreamObserver<Assignment> responseObserver)

Moves an assignment under a new reservation. This differs from removing an existing assignment and recreating a new one by providing a transactional change that ensures an assignee always has an associated reservation.

Parameters
Name Description
request MoveAssignmentRequest
responseObserver io.grpc.stub.StreamObserver<Assignment>

searchAllAssignments(SearchAllAssignmentsRequest request, StreamObserver<SearchAllAssignmentsResponse> responseObserver)

public default void searchAllAssignments(SearchAllAssignmentsRequest request, StreamObserver<SearchAllAssignmentsResponse> responseObserver)

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

  1. Assignments created on the project will be returned if they exist.
  2. Otherwise assignments created on the closest ancestor will be returned.
  3. Assignments for different JobTypes will all be returned. The same logic applies if the request is about a folder. If the request is about an organization, then assignments created on the organization will be returned (organization doesn't have ancestors). Comparing to ListAssignments, there are some behavior differences:
  4. permission on the assignee will be verified in this API.
  5. Hierarchy lookup (project->folder->organization) happens in this API.
  6. Parent here is projects/*/locations/*, instead of projects/*/locations/*reservations/*.
Parameters
Name Description
request SearchAllAssignmentsRequest
responseObserver io.grpc.stub.StreamObserver<SearchAllAssignmentsResponse>

searchAssignments(SearchAssignmentsRequest request, StreamObserver<SearchAssignmentsResponse> responseObserver) (deprecated)

Parameters
Name Description
request SearchAssignmentsRequest
responseObserver io.grpc.stub.StreamObserver<SearchAssignmentsResponse>

splitCapacityCommitment(SplitCapacityCommitmentRequest request, StreamObserver<SplitCapacityCommitmentResponse> responseObserver)

public default void splitCapacityCommitment(SplitCapacityCommitmentRequest request, StreamObserver<SplitCapacityCommitmentResponse> responseObserver)

Splits capacity commitment to two commitments of the same plan and commitment_end_time. A common use case is to enable downgrading commitments. For example, in order to downgrade from 10000 slots to 8000, you might split a 10000 capacity commitment into commitments of 2000 and 8000. Then, you delete the first one after the commitment end time passes.

Parameters
Name Description
request SplitCapacityCommitmentRequest
responseObserver io.grpc.stub.StreamObserver<SplitCapacityCommitmentResponse>

updateAssignment(UpdateAssignmentRequest request, StreamObserver<Assignment> responseObserver)

public default void updateAssignment(UpdateAssignmentRequest request, StreamObserver<Assignment> responseObserver)

Updates an existing assignment. Only the priority field can be updated.

Parameters
Name Description
request UpdateAssignmentRequest
responseObserver io.grpc.stub.StreamObserver<Assignment>

updateBiReservation(UpdateBiReservationRequest request, StreamObserver<BiReservation> responseObserver)

public default void updateBiReservation(UpdateBiReservationRequest request, StreamObserver<BiReservation> responseObserver)

Updates a BI reservation. Only fields specified in the field_mask are updated. A singleton BI reservation always exists with default size 0. In order to reserve BI capacity it needs to be updated to an amount greater than 0. In order to release BI capacity reservation size must be set to 0.

Parameters
Name Description
request UpdateBiReservationRequest
responseObserver io.grpc.stub.StreamObserver<BiReservation>

updateCapacityCommitment(UpdateCapacityCommitmentRequest request, StreamObserver<CapacityCommitment> responseObserver)
