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

getBiReservation(GetBiReservationRequest request, StreamObserver<BiReservation> responseObserver)

public default void getBiReservation(GetBiReservationRequest request, StreamObserver<BiReservation> responseObserver)

Retrieves a BI reservation.

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

getCapacityCommitment(GetCapacityCommitmentRequest request, StreamObserver<CapacityCommitment> responseObserver)

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

Returns information about the capacity commitment.

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

getReservation(GetReservationRequest request, StreamObserver<Reservation> responseObserver)

public default void getReservation(GetReservationRequest request, StreamObserver<Reservation> responseObserver)

Returns information about the reservation.

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

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)

public default void listCapacityCommitments(ListCapacityCommitmentsRequest request, StreamObserver<ListCapacityCommitmentsResponse> responseObserver)

Lists all the capacity commitments for the admin project.

Parameters
Name	Description
request	ListCapacityCommitmentsRequest
responseObserver	io.grpc.stub.StreamObserver<ListCapacityCommitmentsResponse>

listReservations(ListReservationsRequest request, StreamObserver<ListReservationsResponse> responseObserver)

public default void listReservations(ListReservationsRequest request, StreamObserver<ListReservationsResponse> responseObserver)

Lists all the reservations for the project in the specified location.

Parameters
Name	Description
request	ListReservationsRequest
responseObserver	io.grpc.stub.StreamObserver<ListReservationsResponse>

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)

public default void searchAssignments(SearchAssignmentsRequest request, StreamObserver<SearchAssignmentsResponse> responseObserver)

Deprecated: 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/*. Note "-" cannot be used for projects nor locations.

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)

public default void updateCapacityCommitment(UpdateCapacityCommitmentRequest request, StreamObserver<CapacityCommitment> responseObserver)

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

updateReservation(UpdateReservationRequest request, StreamObserver<Reservation> responseObserver)

public default void updateReservation(UpdateReservationRequest request, StreamObserver<Reservation> responseObserver)
