AWS Lambda 函数返回相同的值，除非重新部署

Question

我有一个连接到 mysql rds 的简单 AWS Lambda 函数。当我在我的应用程序 UI 中更新一个字段时，它会在从 MySQL 工作台查看时在数据库中更新它，但是当使用 Lambda 函数时，它会返回相同的值，直到我重新部署该函数，然后它会为我提供新的正确值

"""Search Function for Lambda""" 

from urllib.parse import unquote
import json
import pymysql

# Configuration Values
##CONFIG VALUES REMOVED


# Connection
connection = pymysql.connect(ENDPOINT, user=USERNAME,
                             passwd=PASSWORD, db=DATABASE_NAME)


def get(event, context):
    """Takes searches key from event and searches the database on that key"""
    print(context)
    cursor = connection.cursor()
    search_key = unquote(event['pathParameters']['search_key'])
    cmd = ('SELECT * from LCI_Data WHERE Description Like "{}"'.format("%"+search_key+"%"))
    cursor.execute(cmd)
    result = [dict((cursor.description[i][0], value)
              for i, value in enumerate(row)) for row in cursor.fetchall()]

    response = {
                "statusCode": 200,
                "body": json.dumps(result),
                "headers": {
                    "Access-Control-Allow-Origin": "*",
                    "Access-Control-Allow-Credentials": "true"
                }
            }
    return response

移动

connection = pymysql.connect(ENDPOINT, user=USERNAME,
                             passwd=PASSWORD, db=DATABASE_NAME) 

进入 get() 函数解决了我的问题。
