在Bigquery中,可以使用Cloud KMS提供的功能对列级数据进行加密。以下是一个示例,展示如何在Bigquery的数据表中使用Cloud KMS加密。
首先,在Google Cloud Console中启用Cloud KMS API并创建一个密钥环和密钥。替换下面的'keyring-name”和'key-name”以反映您的密钥环和密钥。
gcloud services enable cloudkms.googleapis.com
gcloud kms keyrings create keyring-name --location global
gcloud kms keys create key-name --location global --keyring keyring-name --purpose encryption
安装并使用Google Cloud SDK(gcloud)来为Bigquery表启用列级加密。此示例使用名为'mydataset”的数据集和'mytable”的表。
# Enable KMS for the dataset
bq update \
--dataset \
--kms_key \
key_name=keyring-name/key-name \
myprojectid:mydataset
# Enable KMS for the table
bq update \
--table \
--kms_key \
key_name=keyring-name/key-name \
myprojectid:mydataset.mytable
现在,您可以使用带有列级加密的Bigquery表进行流插入。以下是一个示例,展示如何使用Cloud Pub/Sub将消息发送到Bigquery。
创建一个新的订阅以接收消息,并用以下代码启动一个模拟器以模拟消息的发送:
import time
from google.cloud import pubsub_v1
project_id = "your-project-id"
topic_name = "your-topic-name"
subscription_name = "your-subscription-name"
# create a topic if it does not exist
publisher = pubsub_v1.PublisherClient()
topic_path = publisher.topic_path(project_id, topic_name)
try:
publisher.create_topic(topic_path)
except Exception:
pass # ignore any errors
# create subscription to consume messages
subscriber = pubsub_v1.SubscriberClient()
subscription_path = subscriber.subscription_path(project_id, subscription_name)
try:
subscriber.create_subscription(subscription_path, topic_path)
except Exception:
pass # ignore any errors
# Send a message to the topic every 1 second
while True:
message = b"Hello, World!"
publisher.publish(topic_path, message=message)
print(f"Sent message: {message}")
time.sleep(1.0)
接下来,使用以下代码将Google Cloud Pub/Sub中的消息提取到Bigquery表中:
from google.cloud import bigquery
from google
