You are tasked with deploying a set of Python UDFs and UDTFs to a Snowflake environment using Snowpark. These functions rely on several external Python packages and need to be versioned and managed effectively. Which of the following strategies provides the MOST robust and scalable solution for managing dependencies and deploying these functions in a reproducible manner?
Correct Answer: B,C
Options B and C provide the most robust and scalable solution. Creating a conda environment specification file (environment.yml) allows for precise control over dependencies and their versions. Both allow other devs to work with the same environment. Uploading the yml allows to include it as a part of snowflake's udfs and udtfs. The difference is whether it can be done directly in snowpark (B) or through the CLI (C). Option A is less manageable as dependencies grow and is prone to manual errors. Option D is not the correct way to handle dependencies for UDFs/UDTFs; the 'imports' parameter is used for data files and other resources, not for installing Python packages.
