If you dont specify the authenticator parameter, under the hood, Snowflake will use its internal (default) authenticator. Tell us in the comments below! The problem with #2 is that you missed a closure. I am working on a notebook on a SageMaker instance at my work. See Using Key Pair Authentication for steps to create the private and public keys. For example, alembic on top of SQLAlchemy manages database schema migrations. However, for convenience, you can use the snowflake.sqlalchemy.URL method to construct the connection string and connect to the database: As you can see, in order to connect with an externalbrowser authentication, the parameters you should specify are exactly the same as with the snowflake.connector. Or is it in (python3)? The connect_args is part of the sqlalchemy.crate_engine call, not the snowflake.sqlalchemy.URL one. This can be easily achieved by passing both engine_2 and a sql query to the pandas read_sql() function: Therefore, If you plan to work with pandas a lot, I would recommend you to connect to Snowflake with sqlalchemy to take advantage of these built-n methods.

You probably noticed that using SQLAlchemy to interface with Snowflake from Python is superior to using the default connector in terms of simplicity. Upon a complete walkthrough of this article, you will gain a decent understanding of Snowflake.

So you need to be careful about how many nested subqueries there are and how you use CTEs etc in complex queries this can lead up to 10x slowdowns. It is possible to connect to Snowflake through two ways in Python. When you run the code above, it returns a connection object con_eb that in turn has a method named cursor().
