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 application that uses a Python UDF to perform complex string manipulations on a large dataset. The current implementation uses a scalar UDF. You are considering converting it to a vectorized UDF. What are the key considerations and potential limitations you need to address during the conversion to ensure correctness and optimal performance? Choose all that apply:

  • A. The vectorized UDF must be able to handle NULL values gracefully within the input arrays, as these can cause errors if not explicitly addressed.
  • B. The input and output data types of the vectorized UDF must exactly match the corresponding column data types in the Snowpark DataFrame.
  • C. The vectorized UDF should utilize libraries like NumPy or Pandas for efficient array processing, but it's important to be aware of the limitations on available Python packages in the Snowflake environment.
  • D. The vectorized UDF's return type must be compatible with Snowpark's data types, and the UDF should return an array of the appropriate type with the same length as the input arrays.
  • E. Vectorized UDFs always perform better than scalar UDFs, regardless of the complexity of the string manipulations or the size of the dataset.

正解：A、C、D

解説：
A, B, and C are all crucial considerations. Vectorized UDFs need to handle NULLs, leverage efficient array processing libraries (while respecting package limitations), and maintain type compatibility and consistent array lengths. D is incorrect, as the performance benefit depends on the workload. For very small datasets or simple operations, the overhead of vectorization might outweigh the benefits. E is partially true. Data type compatability is needed, however, you can cast data type to ensure compatibility.


質問 # 319
You are working with a Snowpark DataFrame called 'customer df that contains customer data, including a column named 'registration_date' of data type TIMESTAMP NTZ. You need to filter the DataFrame to only include customers who registered in the year 2023. Which of the following Snowpark code snippets represents the MOST efficient and correct way to accomplish this filtering, considering potential timezone issues?

  • A.
  • B.
  • C.
  • D.
  • E.

正解：B

解説：
Option C is the most efficient and accurate. It directly compares the 'registration_date' (TIMESTAMP_NTZ) to the date range using string literals, avoiding unnecessary function calls Cyear', 'to_date', 'to_varchar', that could impact performance or introduce subtle errors related to timezone conversions. Since TIMESTAMP_NTZ has no timezone, direct comparison is safe and optimal. Options A and E, while seemingly straightforward, involve function calls for each row, which can be slower. Option B uses 'like' on a date converted to string, which is less efficient and can be problematic with different date formats. Option D converts the date to a VARCHAR, which is unnecessary and impacts performance.


質問 # 320
You are tasked with setting up Snowpark sessions using environment variables defined in a .env' file. You have successfully installed the 'python-dotenv' package and configured your .env' file with the necessary Snowflake connection parameters. However, when your Snowpark application attempts to create a session, it fails with a connection error. Which of the following could be the possible reasons for the failure, assuming you are correctly using 'os.getenv' to access the environment variables?

  • A. The .env' file is not located in the same directory as the Python script.
  • B. The Snowflake account identifier specified in the ' .env' file is incorrect or inaccessible from the network where the Snowpark application is running.
  • C. The required environment variables (e.g., 'SNOWFLAKE_USER, SNOWFLAKE_PASSWORD, 'SNOWFLAKE_ACCOUNT) are not defined or are incorrectly named in the ' .env' file.
  • D. The warehouse defined in your session creation code does not exist or the role defined in the 'snowflake.connector.connect' does not have appropriate warehouse privileges.
  • E. The 'python-dotenv' package was installed, but the ' .env' file wasn't loaded by calling before creating the session.

正解：B、C、D、E

解説：
The correct answers are B, C, D, and E. A Snowpark session creation can fail for multiple reasons related to environment variables. B: Incorrect or missing environment variables in the .env' file will cause the connection to fail. C: Failing to call ' will prevent the environment variables from being loaded, leading to the connection error. D: An incorrect account identifier or network inaccessibility will prevent a connection from being established. E: If the defined warehouse doesn't exist, the session creation will fail due to Snowflake resource constraints. A, stating the file must be in the same directory is incorrect as the path can be specified to the function.


質問 # 321
A data engineering team has developed a Snowpark Python application to process customer orders, enrich them with external data (e.g., geo location, weather) and update the Customer360 table. The application is deployed to a production environment. The application's latency has significantly increased over the last week. Your investigation reveals that the Snowflake warehouse used by the application is constantly switching between the 'Scaling Up' and 'Scaling Down' states. The team has set the Auto Suspend time to 5 minutes and Auto Resume to True. Assuming that the team hasn't changed the code, the external API or any parameter related to data ingestion, which combination of the following actions would MOST likely fix the warehouse instability issue and improve the performance of this Snowpark application in production without substantial cost increases?

  • A. Reduce the MAX CLUSTER COIJNT to limit the potential peak capacity of the warehouse, preventing excessive resource allocation.
  • B. Implement workload management and classification to ensure the Customer360 updates are prioritized over less important tasks and assigned to a dedicated resource pool.
  • C. Increase the Auto Suspend value from 5 minutes to 30 minutes. This will ensure that the warehouse remains active for a longer period, preventing frequent auto- suspends and subsequent resume operations.
  • D. Increase the MIN_CLUSTER_COUNT of the warehouse. This pre-warms clusters and helps the warehouse to quickly adjust to workload changes.
  • E. Change the scaling policy of the warehouse to 'ECONOMY', prioritizing cost efficiency over performance responsiveness.

正解：C、D

解説：
The 'Scaling Up' and 'Scaling Down' thrashing is likely caused by the warehouse suspending too quickly, leading to constant restarts as new requests arrive. Increasing the Auto Suspend time (Option A) prevents this frequent cycling. Increasing the MIN CLUSTER COUNT (Option B) makes more resources readily available, helping the warehouse respond faster to spikes in demand and reducing the need for scaling up. Workload management (Option C) is a good practice but may not directly address the root cause of the instability. Reducing MAX_CLUSTER_COUNT (Option D) could worsen the problem by limiting the warehouse's ability to handle peak loads. Changing to 'ECONOMY' scaling policy (Option E) would prioritize cost over performance, which is counter to improving performance.


質問 # 322
You are working with image files stored in a Snowflake internal stage named 'image_stage'. You need to write a Snowpark Python application to resize these images using a Python library called 'PIG. The resizing logic is encapsulated in a function called resize_image(snowflake_file: SnowflakeFile, width: int, height: int) -> bytes. Which of the following code snippets correctly registers he 'resize image' function as a UDF and applies it to the image files?

  • A.
  • B.
  • C.
  • D.
  • E.

正解：D

解説：
Option E correctly implements the image resizing using Snowpark UDF and 'SnowflakeFile' object. - The 'resize_image' function takes the as input and constructs the SnowflakeFile object correctly - 'SnowflakeFile.from_path('@image_stage', file_path)' correctly creates Snowflake file object based on provided file path - The UDF registration specifies the correct input type 'StringType' for file path , BinaryType' for the return and includes the 'pillow' package. - The final select statement calls the UDF correctly with the 'relative_path' column. Option D is incorrect because 'f.readall()' returns bytes, and PIL.lmage.open expects a file-like object or filename, wrapping this within ByteslO is unnecessary. Option B is wrong because the snowflake file object should be created in the python function itself, UDF creation and calling both are wrong Option A and C have registration issue for packages, as it is not provided to function registration.
