关闭 Snowflake DB 日志记录，同时仍将日志级别保持为 DEBUG答案

【问题标题】：Turning off Snowflake DB logging while still keeping log level as DEBUG关闭 Snowflake DB 日志记录，同时仍将日志级别保持为 DEBUG
【发布时间】：2019-10-24 18:58:55
【问题描述】：

是否可以禁用 Snowflake SQL 日志记录，该日志记录数据库连接的开始和结束以及正在执行的所有查询，同时保留 logging.basicConfig(level=logging.INFO) 以调试我的开发。

也许这不是 Snowflake 特有的，而是来自 Python 的一般数据库连接？

我正在使用snowflake-connector-python 1.8.1 版

我目前拥有的简化日志示例。

标签： python logging database-connection snowflake-cloud-data-platform

【解决方案1】：

在导入 snowflake.connector 的 Python 模块中，在调用连接器上的任何方法之前，添加

logging.getLogger('snowflake.connector').setLevel(logging.WARNING)

让它只记录警告或更高级别。

我发现@john Velonis 的解决方案并没有完全摆脱所有雪花消息。我仍然收到这样的消息：

我认为这些来自CPP code here。要将这些也静音，我还必须将snowflake.connector.CArrowIterator 设置为更高的日志级别。我使用了这样的代码：

import logging
for name in logging.Logger.manager.loggerDict.keys():
    if 'snowflake' in name:
        logging.getLogger(name).setLevel(logging.WARNING)
        logging.getLogger(name).propagate = False

【解决方案3】：

试试这个

logging.getLogger('snowflake.connector.connection').propagate=False
