可以尝试以下方法解决该问题:
代码示例:
# 异步执行查询请求
from google.cloud import bigquery
from concurrent.futures import TimeoutError
import time
# 初始化BigQuery客户端
client = bigquery.Client()
# 异步查询
query = """
SELECT x, y
FROM `myproject.mydataset.mytable`
"""
query_job = client.query(query)
# 等待执行结果
while not query_job.done():
print('Waiting for job to complete...')
time.sleep(1)
# 获取查询结果
results = query_job.result()
# 处理结果
for row in results:
print(row)
# 缓存查询结果
from google.cloud import storage
# 初始化存储客户端
bucket_name = 'my-bucket'
storage_client = storage.Client()
bucket = storage_client.bucket(bucket_name)
# 上传文件到存储桶
blob = bucket.blob('result.csv')
blob.upload_from_filename('path/to/result.csv')
# 从存储桶下载文件
blob = bucket.blob('result.csv')
blob.download_to_filename('path/to/result.csv')
