A company’s platform team wants to integrate their existing data lake with Snowflake. The data lake is hundreds of TBs in size and the team does not want to duplicate most of the data into Snowflake.

D Create an external table for each corresponding data lake table to enable querying data stored in files in the data lake as if the data lake table was inside a database.

Which characteristic applies to Snowpark Python stored procedures?

A They must return a value.
