Turning off Snowflake DB logging while still keeping log level as DEBUG

Question

Is it possible to disable the Snowflake SQL logging which logs the start and end of a DB connection and all the queries being executed while keeping logging.basicConfig(level=logging.INFO) for debugging my development.

Maybe this is not specific to Snowflake but a general DB connection from Python?

I'm using snowflake-connector-python version 1.8.1

Sample simplified log that I currently have.

Answer 1

In your Python module that imports snowflake.connector, before you call any methods on the connector, add

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

to have it log only warnings or higher levels.

I find that @john Velonis' solution doesn't quite get rid of all snowflake messages. I was still getting messages like this:

2020-03-26 18:03:04    DEBUG:   cursor.fetchone:824 - Current batch index

I think these come from some CPP code here. To mute these too, I also had to set snowflake.connector.CArrowIterator to a higher log level. I used code like this:

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
