Exam DEA-C02 Topic 1 Question 264 Discussion

Actual exam question for Snowflake's DEA-C02 exam
Question #: 264
Topic #: 1

You are developing a JavaScript stored procedure in Snowflake using Snowpark to perform a complex data transformation. This transformation involves multiple steps: filtering, joining with another table, and aggregating data'. You need to ensure that the stored procedure is resilient to failures and can be easily debugged. Which of the following practices would contribute to the robustness and debuggability of your stored procedure? (Select all that apply)

A. Relying solely on try-catch blocks within the stored procedure to handle all potential exceptions. B. Using Snowpark's logging capabilities to record intermediate results and error messages at various stages of the transformation. C. Breaking down the complex transformation into smaller, modular functions within the stored procedure and testing each function independently. D. Passing the 'snowflake' binding as an argument to each modular function to facilitate logging and SQL execution within those functions. E. Directly manipulating the Snowflake metadata (e.g., table schemas) within the stored procedure for dynamic schema evolution.

Suggested Answer: B,C,D Vote an answer

Options B, C, and D are correct. Logging intermediate results allows you to track the flow of data and identify the point of failure. Modularizing the code and testing individual functions makes debugging easier. Passing the 'snowflake' binding allows each module to log and execute SQL. Option A is insufficient, complex error requires more granular logging. Option E is dangerous and should be avoided as metadata changes should ideally be performed outside of transformation stored procedure and should be managed by orchestration tools.
