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.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

CreateAssignment(std::string const &, google::cloud::bigquery::reservation::v1::Assignment const &, Options)

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.

The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.bigquery.reservation.v1.Assignment, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListAssignments(google::cloud::bigquery::reservation::v1::ListAssignmentsRequest, Options)

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	google::cloud::bigquery::reservation::v1::ListAssignmentsRequest Unary RPCs, such as the one wrapped by this function, receive a single request proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.reservation.v1.ListAssignmentsRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
opts	Options Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
StreamRange< google::cloud::bigquery::reservation::v1::Assignment >	a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.bigquery.reservation.v1.Assignment, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

DeleteAssignment(std::string const &, Options)

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
name	std::string const & Required. Name of the resource, e.g. projects/myproject/locations/US/reservations/team1-prod/assignments/123
opts	Options Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
Status	a Status object. If the request failed, the status contains the details of the failure.

SearchAssignments(std::string const &, std::string const &, Options)

Deprecated: This RPC is 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.

Parameters
Name	Description
parent	std::string const & Required. The resource name of the admin project(containing project and location), e.g.: projects/myproject/locations/US.
