建立預留項目群組

在特定專案和位置建立預留項目群組。預留項目群組是 BigQuery 預留項目的容器。

程式碼範例

Node.js

在試用這個範例之前，請先按照「使用用戶端程式庫的 BigQuery 快速入門導覽課程」中的 Node.js 設定說明操作。詳情請參閱 BigQuery Node.js API 參考說明文件。

如要向 BigQuery 進行驗證，請設定應用程式預設憑證。詳情請參閱「設定用戶端程式庫的驗證作業」。

const {ReservationServiceClient} =
  require('@google-cloud/bigquery-reservation').v1;
const {status} = require('@grpc/grpc-js');

const client = new ReservationServiceClient();

/**
 * Creates a new reservation group.
 * A reservation group is a container for reservations. This can be useful for
 * managing reservations for different teams or workloads.
 *
 * @param projectId Google Cloud project ID, for example 'example-project-id'.
 * @param location The Google Cloud location where the reservation group will be created, for example 'us-central1'.
 * @param reservationGroupId The ID to use for the reservation group, for example 'example-reservation-group'.
 */
async function createReservationGroup(projectId,
  location = 'us-central1',
  reservationGroupId = 'example-group-reservation',) {
  const request = {
    parent: `projects/${projectId}/locations/${location}`,
    reservationGroupId,
    reservationGroup: {},
  };

  try {
    const [reservationGroup] = await client.createReservationGroup(request);
    console.log(`Created reservation group: ${reservationGroup.name}`);
  } catch (err) {
    if (err.code === status.ALREADY_EXISTS) {
      console.log(
        `Reservation group '${reservationGroupId}' already exists in project '${projectId}' in location '${location}'.`,
      );
    } else {
      console.error('Error creating reservation group:', err);
    }
  }
}

Python

在試用這個範例之前，請先按照「使用用戶端程式庫的 BigQuery 快速入門導覽課程」中的 Python 設定說明操作。詳情請參閱 BigQuery Python API 參考說明文件。

如要向 BigQuery 進行驗證，請設定應用程式預設憑證。詳情請參閱「設定用戶端程式庫的驗證作業」。
