Snowflake Certified SnowPro Specialty - Snowpark 認定 SPS-C01 試験問題 (Q318-Q323):

質問 # 318
You are tasked with optimizing a Snowpark Python application that performs complex data transformations on a large dataset. The application is running slower than expected, and you suspect that data serialization and transfer between the Snowpark client and the Snowflake engine are bottlenecks. Which of the following strategies could you implement to improve performance? (Select all that apply.)

A. Create and utilize temporary tables within Snowflake to store intermediate results of complex transformations.
B. Increase the configuration parameter to maximize parallelism within the Snowpark engine without considering resources or potential bottleneck.
C. Minimize the amount of data transferred between the client and the engine by pushing down as much computation as possible to Snowflake using Snowpark DataFrame operations.
D. Utilize smaller batch sizes when writing data back to Snowflake to reduce memory pressure on the client.
E. Convert all dataframes to Pandas dataframes locally and perform data manipulation with Pandas methods to take advantage of local resources.

正解：A、C、D

解説：
Options A, B, and C are correct strategies. Pushing down computation (A) reduces data transfer. Using smaller batch sizes (B) can reduce memory pressure, especially for large datasets. Using temporary tables (C) allows intermediate results to be stored and processed entirely within Snowflake, avoiding unnecessary data transfer. Option D is incorrect because converting to Pandas DataFrames brings the data to the client, negating the benefits of Snowpark's distributed processing. Option E is dangerous since it could cause bottleneck if the resources are not managed correctly.

質問 # 319
You have a Snowpark DataFrame named 'orders_df with columns 'order_id', 'customer_id', 'order_date', and 'order_total'. You need to perform the following data enrichment steps using Snowpark for Python: 1. Calculate the 'year' from the 'order_date' column. 2. Calculate the 'discounted_total' by applying a discount of 10% if the 'order_total' is greater than $100, otherwise, no discount. 3. Create a new column 'customer_tier' based on the total spend per customer for each year. Customers with total spend greater than $1000 are 'Gold', between $500 and $1000 are 'Silver', and below $500 are 'Bronze'. Which of the following code snippets correctly implements these data enrichment steps using Snowpark (Assume the existence of a customer total spend df DataFrame).

正解：C

解説：
Option B is the most efficient and correct. It calculates 'year' and 'discounted_total' using built-in functions. It then groups by 'customer_id' and 'year' to calculate 'total_spend'. Critically, it then assigns the 'customer_tier' using a series of 'when' statements directly within Snowpark, avoiding the performance overhead of a UDE Finally, it joins the customer tier information back to the original 'orders df. Option A implements Customer Tier calculation using UDF, Option C introduces Windowing without need. Options D, E are incomplete.

質問 # 320
You are developing a Snowpark application that performs several complex transformations on a large DataFrame representing customer purchase history. This DataFrame is used multiple times in the application. You need to optimize the application's performance by caching the DataFrame. Which of the following approaches is the MOST efficient and memory-conscious way to cache the DataFrame in Snowpark?

A. Using without specifying a storage level. Snowflake will choose a default storage level.
B. Creating a temporary table in Snowflake using and then reading it back into a new DataFrame for each subsequent operation.
C. Using to store the entire DataFrame in a Python list, then creating a new DataFrame from that list for each subsequent operation.
D. Using 'session.createDataFrame(df.toPandas())' to convert the Snowpark DataFrame to Pandas and back to Snowpark DataFrame.
E. Using immediately after the initial DataFrame creation.

正解：E

解説：
' df.cache_result()' is the recommended approach for caching DataFrames in Snowpark. It is designed to efficiently materialize the results of a DataFrame and store them in Snowflake's internal cache. This avoids recomputation in subsequent operations. brings the entire DataFrame into the client's memory, which is inefficient for large datasets. is not directly available in Snowpark like Spark. Creating a temporary table involves unnecessary I/O operations. Converting to Pandas and back introduces overhead and defeats the purpose of using Snowpark's optimized execution.

質問 # 321
You have written a Snowpark Python function that utilizes a UDF to perform complex string manipulation on a DataFrame containing customer reviews. When deploying this function using '@sproc.test_utils.mock_snowflake environment, the test fails with a 'ModuleNotFoundError' indicating that a custom Python library (e.g., is not available. You have already confirmed that the library is installed in your local development environment. What is the MOST reliable way to ensure the UDF has access to this dependency during local testing?

A. Manually copy the directory into the 'ltmp' directory on your local machine before running the test. Snowpark will automatically detect libraries in this directory.
B. Use before defining the UDF to explicitly include the library as a zipped file. Ensure the zipped file contains the directory.
C. Append the path to the library to the 'PYTHONPATH' environment variable before executing the local tests. This will make the library available to the Snowpark session during testing.
D. Install the globally on your local machine using 'pip install
E. Include the directory within the same directory as your Snowpark Python function and explicitly import it using a relative path (e.g., 'from .text_processing_lib import ...4).

正解：B

解説：
Option C is the most reliable solution for local testing with . The function explicitly makes the library available to the Snowpark session during execution, simulating how dependencies are handled in the Snowflake environment. Option A might work locally, but it's not a reliable deployment strategy. Option B is a temporary workaround and not a structured solution. Option D makes the library globally available, defeating the purpose of isolating dependencies for testing. Option E is a valid approach but less explicit and may affect other Python environments on the system. Using 'add_import' ensures that the correct version and dependencies are included in the deployment package.

質問 # 322
You are developing a Snowpark stored procedure to perform data transformation. The procedure needs to handle both integers and strings as input parameters and return a DataFrame. Which of the following is the MOST efficient and recommended way to define the data types for the input parameters and the return value, ensuring proper data handling and type safety during deployment and execution?

A. Defining input parameter types using Python type hints (e.g., 'x: int, y: str') and the return type as 'List[Row]' without explicit registration. Snowpark automatically handles conversion.
B. Explicitly registering the stored procedure with 'sproc.registeff and specifying the input types using 'Argument objects and the return type using with schema definition.
C. Relying solely on Snowpark's implicit type inference for both input parameters and the DataFrame return value, avoiding explicit type hints or registration.
D. Using Python type hints for input parameters and relying on Snowpark's implicit type inference for the DataFrame return value.
E. Using Python type hints for input parameters and explicitly registering the stored procedure using 'sproc.register' and specifying the return type using with schema definition.

正解：E

解説：
Explicitly registering the stored procedure with 'sproc.register' and defining the input types using Python type hints (e.g., 'x: int, y: str') and the return type using is the most robust approach. While type hints improve readability and allow for static analysis, registration with explicit return type schema enforces the structure of the returned DataFrame at deployment, ensuring type safety and preventing unexpected runtime errors. This is especially critical in production environments. Using implicit type inference or relying solely on Python hints can lead to unexpected issues if the data doesn't conform to the expected types.
