刪除 BigQuery 預留項目

從 BigQuery Reservation API 刪除預留項目。保留項目不得有任何指派作業。

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('google-gax');

const client = new ReservationServiceClient();

/**
 * Deletes a reservation.
 * A reservation provides computational resource guarantees, in the form of slots, to users.
 * @param {string} projectId The Google Cloud project ID.
 * @param {string} location The geographic location where the reservation resides, for example 'us-central1'.
 * @param {string} reservationId The ID of the reservation to delete, for example 'example-reservation'.
 */
async function deleteReservation(
  projectId,
  location = 'us-central1',
  reservationId = 'example-reservation',
) {
  // Construct the fully-qualified path for the reservation.
  const name = client.reservationPath(projectId, location, reservationId);

  const request = {
    name,
  };

  try {
    await client.deleteReservation(request);
    console.log(`Deleted reservation: ${reservationId}`);
  } catch (err) {
    if (err.code === status.NOT_FOUND) {
      console.log(
        `Reservation ${reservationId} not found in project ${projectId} location ${location}.`,
      );
    } else {
      console.error(`Error deleting reservation ${reservationId}:`, 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」。

from google.api_core.exceptions import NotFound
from google.cloud import bigquery_reservation_v1

client = bigquery_reservation_v1.ReservationServiceClient()


def delete_reservation(project_id: str, location: str, reservation_id: str):
    """Deletes a reservation.

    A reservation can only be deleted if it has no assignments.

    Args:
        project_id: The Google Cloud project ID.
        location: The geographic location of the reservation, for example, "us-central1".
        reservation_id: The ID of the reservation to delete.
    """
    name = client.reservation_path(project_id, location, reservation_id)

    try:
        client.delete_reservation(name=name)
        print(f"Deleted reservation: {name}")
    except NotFound:
        print(f"Reservation '{name}' not found.")
