Class ReservationServiceGrpc.ReservationServiceBlockingStub (2.4.2)

public static final class ReservationServiceGrpc.ReservationServiceBlockingStub extends AbstractBlockingStub<ReservationServiceGrpc.ReservationServiceBlockingStub>

This API allows users to manage their flat-rate 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.

createAssignment(CreateAssignmentRequest request)

public Assignment createAssignment(CreateAssignmentRequest request)

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.
Parameter

deleteAssignment(DeleteAssignmentRequest request)

public Empty deleteAssignment(DeleteAssignmentRequest request)

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.
Parameter
NameDescription
requestDeleteAssignmentRequest
Returns
TypeDescription
Empty

deleteCapacityCommitment(DeleteCapacityCommitmentRequest request)

public Empty deleteCapacityCommitment(DeleteCapacityCommitmentRequest request)

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.

Parameter
NameDescription
requestDeleteCapacityCommitmentRequest
Returns
TypeDescription
Empty

deleteReservation(DeleteReservationRequest request)

public Empty deleteReservation(DeleteReservationRequest request)

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

Returns
TypeDescription
Empty

Returns information about the reservation.

Parameter
NameDescription
requestGetReservationRequest
Returns
TypeDescription
Reservation

listAssignments(ListAssignmentsRequest request)

public ListAssignmentsResponse listAssignments(ListAssignmentsRequest request)

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.
Parameter
NameDescription
requestListAssignmentsRequest
Returns
TypeDescription
ListAssignmentsResponse

listCapacityCommitments(ListCapacityCommitmentsRequest request)

public ListCapacityCommitmentsResponse listCapacityCommitments(ListCapacityCommitmentsRequest request)

Lists all the capacity commitments for the admin project.

Parameter
NameDescription
requestListCapacityCommitmentsRequest
Returns
TypeDescription
ListCapacityCommitmentsResponse

listReservations(ListReservationsRequest request)

public ListReservationsResponse listReservations(ListReservationsRequest request)

mergeCapacityCommitments(MergeCapacityCommitmentsRequest request)

public CapacityCommitment mergeCapacityCommitments(MergeCapacityCommitmentsRequest request)

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.

Parameter
NameDescription
requestMergeCapacityCommitmentsRequest
Returns
TypeDescription
CapacityCommitment

moveAssignment(MoveAssignmentRequest request)

public Assignment moveAssignment(MoveAssignmentRequest request)

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.

Parameter
NameDescription
requestMoveAssignmentRequest
Returns
TypeDescription
Assignment

searchAllAssignments(SearchAllAssignmentsRequest request)

public SearchAllAssignmentsResponse searchAllAssignments(SearchAllAssignmentsRequest request)

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/*.
Parameter
NameDescription
requestSearchAllAssignmentsRequest
Returns
TypeDescription
SearchAllAssignmentsResponse

splitCapacityCommitment(SplitCapacityCommitmentRequest request)

public SplitCapacityCommitmentResponse splitCapacityCommitment(SplitCapacityCommitmentRequest request)

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.

Parameter
NameDescription
requestSplitCapacityCommitmentRequest
Returns
TypeDescription
SplitCapacityCommitmentResponse
