将数据从S3读取到pandas的最佳方法

import pandas as pd
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client

def read_data_from_s3(event, context):
    # 配置腾讯云对象存储（COS）的密钥信息
    secret_id = 'your_secret_id'
    secret_key = 'your_secret_key'
    region = 'your_cos_region'
    bucket = 'your_cos_bucket'

    # 创建COS客户端
    config = CosConfig(Region=region, SecretId=secret_id, SecretKey=secret_key)
    cos_client = CosS3Client(config)

    # 从S3读取数据
    response = cos_client.get_object(Bucket=bucket, Key='your_object_key')
    data = response['Body'].read()

    # 将数据转换为pandas数据帧
    df = pd.read_csv(data)

    # 打印数据帧
    print(df.head())

    # 返回数据帧
    return df
