SNOW-912318: Typed connection URL query parameters get converted to strings

[saulbein]

Please answer these questions before submitting your issue. Thanks!

1. What version of Python are you using?

   Python 3.8.16 (default, Feb 6 2023, 12:05:53)
   [GCC 12.2.1 20230111]

2. What operating system and processor architecture are you using?

   Linux-6.1.38-1-MANJARO-x86_64-with-glibc2.34

3. What are the component versions in the environment (pip freeze)?

   asn1crypto==1.5.1
   certifi==2023.7.22
   cffi==1.15.1
   charset-normalizer==3.2.0
   cryptography==41.0.3
   filelock==3.12.2
   greenlet==2.0.2
   idna==3.4
   oscrypto==1.3.0
   packaging==23.1
   platformdirs==3.8.1
   pycparser==2.21
   pycryptodomex==3.18.0
   PyJWT==2.8.0
   pyOpenSSL==23.2.0
   pytz==2023.3
   requests==2.31.0
   snowflake-connector-python==3.1.0
   -e git+ssh://git@github.com/snowflakedb/snowflake-sqlalchemy.git@de68d864af14200643b74625db4480db87c92172#egg=snowflake_sqlalchemy
   sortedcontainers==2.4.0
   SQLAlchemy==1.4.49
   tomlkit==0.12.1
   typing_extensions==4.7.1
   urllib3==1.26.16
   

4. What did you do?

   Passed a non-string snowflake-connector parameter through the URL query parameters - see SNOW-892284: Boolean URL connection parameters are passed down to the driver as strings #438 for booleans specifically and SNOW-892284: Fix boolean parameter parsing from URL query #439 for the fix for them, though not other types. Parameters like converter_class will still get set incorrectly, causing errors or weird behaviour.

5. What did you expect to see?

   Parameters passed through the URL class should allow passing all python-connector variables through as they are.

6. Can you set logging to DEBUG and collect the logs?

   See SNOW-892284: Boolean URL connection parameters are passed down to the driver as strings #438.

hi and thank you for submitting the issue and your contribution in the PR !
if this is the same issue as #438 , it looks to be fixed with #446

please comment if this is unrelated and still needs to be looked into and i can reopen

This is specifically about other types rather than just booleans - there are also integers and even functions that can be sent to the driver that wouldn't work with snowflake-sqlalchemy.
