SNOW-2684360: Check local environment before wasting useless ressources on cloud checking

[G-Guillard]

What is the current behavior?

On a local machine, initial connection with snowflake.connector.connect takes more than 10 seconds because of detect_platforms (in Auth.base_auth_data()).

What is the desired behavior?

Check whether the code is running on a local machine before trying to detect the cloud platform.

How would this improve snowflake-connector-python?

This would reduce the connection time from more than 10 seconds to about 1 second.

Hello @G-Guillard ,

Thanks for raising the concern.
You can disable the 10-second platform detection timeout by using the property platform_detection_timeout_seconds=0
This is available from Python connector 3.17.2 onwards.

https://docs.snowflake.com/en/release-notes/clients-drivers/python-connector-2025#version-3-17-2-august-20-2025

`import snowflake.connector

conn = snowflake.connector.connect(
user="...",
password="...",
account="...",
# other params...
platform_detection_timeout_seconds=0, # disable platform detection
)`

Thanks, it works indeed. I couldn’t find much information about the platform detection feature, may using this setting in the production environment (i.e. not locally) have any negative consequences ?

Hi @G-Guillard ,

No impact, you can use it.
