SNOW-522232: SAWarning: Dialect snowflake:snowflake will not make use of SQL compilation caching as it does not set the 'supports_statement_cache' attribute to ``True``.

Python 3.8.9 macOS-11.6.2-x86_64-i386-64bit snowflake-connector-python: 2.7.2 snowflake-sqlalchemy: 1.3.3 SQLAlchemy: 1.4.28

I imported the following…

import pandas as pd
from sqlalchemy import create_engine
from snowflake.sqlalchemy import URL
import snowflake.connector

Then, I created a new engine and executed my first query…

url = URL(CREDENTIALS) 
engine = create_engine(url)
connection = engine.connect()

pd.read_sql(QUERY, connection)

Received the following warning…

/Users/NAME/.local/lib/python3.8/site-packages/snowflake/sqlalchemy/snowdialect.py:206: SAWarning: Dialect snowflake:snowflake will not make use of SQL compilation caching as it does not set the ‘supports_statement_cache’ attribute to True. This can have significant performance implications including some performance degradations in comparison to prior SQLAlchemy versions. Dialect maintainers should seek to set this attribute to True after appropriate development and testing for SQLAlchemy 1.4 caching support. Alternatively, this attribute may be set to False which will disable this warning. (Background on this error at: https://sqlalche.me/e/14/cprf)

For those who’d like this warning to be disabled do this before creating an engine:

from snowflake.sqlalchemy.snowdialect import SnowflakeDialect

SnowflakeDialect.supports_statement_cache = False

Could we just set supports_statement_cache to False for now? Preferably in this package, rather than users doing it manually.
