Python AWS Lambda 信号：在雪花连接（snowflake.connector）期间中止（核心转储）

Question

我是 lambda 功能的新手...我正在尝试测试 Lambda function 以连接到雪花。 经过一番研究，我终于把我需要的所有包都压缩并添加到了一个层中。

我在 lambda function 中添加了环境变量，并为密码、用户和帐户调用它们。

在我看来，它一直在循环尝试访问雪花......

我现在得到这个：

Response:
{
  "errorType": "Runtime.ExitError",
  "errorMessage": "RequestId: 76342539-d44a-4732-a027-6d133d3e4ea5 Error: Runtime exited with error: signal: aborted (core dumped)"
}

这是日志：

这是 python 代码：

import os
import sys
sys.path.insert(0, '/opt')
import snowflake.connector as sc
import boto3
import json
acct = os.environ['sf']
user = os.environ['user']
pw = os.environ['pw']

def lambda_handler(event, context):
    sfx = sc.connect(user=user, password=pw,account=acct)
    sf_c = sfx.cursor()
    sf_c.close()
    return {
        'statuscode': 200,
        'body': 'I was here!'
        }
    sfx.close()

任何帮助将不胜感激！

我需要为此配置 VPC 吗？

Answer 1

要将 Lambda 服务与 Snowflake 一起使用，您需要确保您创建的 Python package 具有所需的所有依赖项。 下面的文章逐步解释了如何将 AWS Lambda 与 Snowflake 一起使用。 https://docs.snowflake.com/en/user-guide/data-load-snowpipe-rest-lambda.html

当您在 AWS 账户中启动 Lambda 服务时，默认情况下它会在默认 VPC 中启动。 如果默认 VPC 没有公共 Internet 连接，则连接可能会失败。 因此，请确保您使用可以访问您的雪花公共 URL 的 VPC。
