Consider a DataFrame 'products df loaded from a SnoMlake table. It contains a 'features' column of type VARIANT, where each row contains a JSON object representing product features. Your task is to create a new DataFrame where each feature becomes a separate column. You need to dynamically extract these features without knowing the specific feature names in advance. Which of the following approaches could achieve this using Snowpark, and what considerations are important? Choose all that apply:
Correct Answer: B,C
Options B and C are viable approaches. Option B: You can use the native function on the VARIANT column to extract the keys, then iterate over the returned array to dynamically create new columns. This relies on knowing the structure of the data at runtime, but doesn't require a UDE Option C: FLATTEN' offers a SQL-centric way to achieve this, which might be preferable for performance and maintainability. After flattening, you would typically pivot the data. Option A is possible with IJDFs, but might be less performant than using native functions or FLATTEN. Option D is incorrect; dynamic column creation is possible. While OBJECT_CONSTRUCT() can construct JSON objects, it's not directly helpful for dynamically extracting JSON properties into separate columns in this scenario (Option E).
