Python循环仅在cassandra中插入最后一行

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

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

# 准备插入语句
insert_statement = session.prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)")

# 循环插入数据
for i in range(10):
    session.execute(insert_statement, (i, 'value'))

# 等待写入完成
session.execute(SimpleStatement("SELECT * FROM table_name"))

# 关闭连接
session.shutdown()
cluster.shutdown()

import time

# 循环插入数据
for i in range(10):
    session.execute(insert_statement, (i, 'value'))
    time.sleep(0.1)  # 添加0.1秒的延迟
