在Python中为Cassandra生成UUID

import uuid
from cassandra.query import SimpleStatement
from cassandra import ConsistencyLevel
from cassandra.cluster import Cluster

# 连接到Cassandra集群
cluster = Cluster(['127.0.0.1'])
session = cluster.connect('your_keyspace')

# 定义一个UUID生成器
def generate_uuid():
    return uuid.uuid4()

# 定义一个插入数据的函数
def insert_data(id, name):
    query = """
        INSERT INTO your_table (id, name) VALUES (%s, %s)
    """
    session.execute(query, (id, name), consistency_level=ConsistencyLevel.ONE)

# 生成UUID并插入数据
id = generate_uuid()
insert_data(id, 'John Doe')

# 关闭Cassandra连接
cluster.shutdown()
