Package com.google.cloud.bigquery.reservation.v1

Class ReservationServiceGrpc.ReservationServiceStub

  • Enclosing class:
    ReservationServiceGrpc
    public static final class ReservationServiceGrpc.ReservationServiceStub
extends io.grpc.stub.AbstractAsyncStub<ReservationServiceGrpc.ReservationServiceStub>
    A stub to allow clients to do asynchronous rpc calls to service ReservationService. 
     This API allows users to manage their 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`.

      • createReservation

        public void createReservation​(CreateReservationRequest request,
                              io.grpc.stub.StreamObserver<Reservation> responseObserver)
         Creates a new reservation resource.

      • getReservation

        public void getReservation​(GetReservationRequest request,
                           io.grpc.stub.StreamObserver<Reservation> responseObserver)
         Returns information about the reservation.

      • deleteReservation

        public void deleteReservation​(DeleteReservationRequest request,
                              io.grpc.stub.StreamObserver<com.google.protobuf.Empty> responseObserver)
         Deletes a reservation.
 Returns `google.rpc.Code.FAILED_PRECONDITION` when reservation has
 assignments.

      • updateReservation

        public void updateReservation​(UpdateReservationRequest request,
                              io.grpc.stub.StreamObserver<Reservation> responseObserver)
         Updates an existing reservation resource.

      • deleteCapacityCommitment

        public void deleteCapacityCommitment​(DeleteCapacityCommitmentRequest request,
                                     io.grpc.stub.StreamObserver<com.google.protobuf.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`.

      • updateCapacityCommitment

        public void updateCapacityCommitment​(UpdateCapacityCommitmentRequest request,
                                     io.grpc.stub.StreamObserver<CapacityCommitment> responseObserver)
         Updates an existing capacity commitment.
 Only `plan` and `renewal_plan` fields can be updated.
 Plan can only be changed to a plan of a longer commitment period.
 Attempting to change to a plan with shorter commitment period will fail
 with the error code `google.rpc.Code.FAILED_PRECONDITION`.

      • splitCapacityCommitment

        public void splitCapacityCommitment​(SplitCapacityCommitmentRequest request,
                                    io.grpc.stub.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.

      • mergeCapacityCommitments

        public void mergeCapacityCommitments​(MergeCapacityCommitmentsRequest request,
                                     io.grpc.stub.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`.

      • createAssignment

        public void createAssignment​(CreateAssignmentRequest request,
                             io.grpc.stub.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.

      • listAssignments

        public void listAssignments​(ListAssignmentsRequest request,
                            io.grpc.stub.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.

      • deleteAssignment

        public void deleteAssignment​(DeleteAssignmentRequest request,
                             io.grpc.stub.StreamObserver<com.google.protobuf.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.

      • searchAssignments

        @Deprecated
public void searchAssignments​(SearchAssignmentsRequest request,
                              io.grpc.stub.StreamObserver<SearchAssignmentsResponse> responseObserver)
        Deprecated.
         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:
 1. permission on the assignee will be verified in this API.
 2. Hierarchy lookup (project->folder->organization) happens in this API.
 3. Parent here is `projects/*/locations/*`, instead of
    `projects/*/locations/*reservations/*`.
 **Note** "-" cannot be used for projects
 nor locations.

      • searchAllAssignments

        public void searchAllAssignments​(SearchAllAssignmentsRequest request,
                                 io.grpc.stub.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).

      • moveAssignment

        public void moveAssignment​(MoveAssignmentRequest request,
                           io.grpc.stub.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.

      • updateAssignment

        public void updateAssignment​(UpdateAssignmentRequest request,
                             io.grpc.stub.StreamObserver<Assignment> responseObserver)
         Updates an existing assignment.
 Only the `priority` field can be updated.

      • updateBiReservation

        public void updateBiReservation​(UpdateBiReservationRequest request,
                                io.grpc.stub.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.
