질문 # 175
You are optimizing a Snowpark Python application that performs complex data transformations on a large dataset. You notice significant performance bottlenecks. Which of the following optimization techniques would be MOST effective in leveraging the Snowpark architecture to improve performance?
정답：D
설명：
Lazy evaluation (C) is a key optimization strategy in Snowpark. By chaining transformations, Snowpark can optimize the execution plan and push down operations to the Snowflake engine for efficient processing. Converting to Pandas DataFrames (A) brings data out of Snowflake, negating the benefits of the engine. While vectorized UDFs (B) can be useful, they may not always be as efficient as optimized native Snowpark functions. Manual partitioning (D) is usually handled automatically by Snowflake. session.sql() can bypass optimizations available to Snowpark.
질문 # 176
You have JSON files stored in an internal stage named 'json_stage' within your Snowflake account. Each JSON file contains an array of product objects, with potentially nested structures. You need to create a Snowpark DataFrame to analyze this data, but the schema is complex and you want to avoid explicitly defining it in your Python code. Which of the following Snowpark code snippets will MOST effectively achieve this, assuming you have a Snowpark session object named 'session'?
정답：A
설명：
Option A is the most straightforward. By default, Snowpark automatically infers the schema when reading JSON files directly from a stage without requiring additional options. Other options are useful for specific cases, like handling missing fields, but are not necessary for the basic requirement of reading JSON with schema inference. Note that E would require looping through and UNIONing results, and is far less efficient than the built in stage reader.
질문 # 177
A financial firm is using Snowpark Python to analyze stock trading data'. They have a DataFrame named 'trades' with columns 'trade_id', 'stock_symbol', 'trade_price', and 'trade_timestamp'. They want to identify potentially fraudulent trades based on the following criteria: 1. Trades where the 'trade_price' deviates significantly from the average price of that 'stock_symbol' over the past hour. 2. Trades originating from user accounts where the price is above $1000.3. Trades which has stock symbol 'XYZ'. The firm wants to apply multiple filters to the DataFrame to extract only the fraudulent trades and needs an efficient and concise approach using Snowpark. Which of the following code snippets, using 'trade_price' > 1000 as user identifier, MOST accurately and efficiently implements this filtering logic? Assume that a Snowflake user has a maximum amount they can spend on a trade, and therefore, the user ID is associated with 'trade_price'.
정답：B
설명：
The most efficient and accurate solution is Option B. Here's why: Efficiency: It calculates the average price within the window using and the 'over' clause only once, storing this in a new column called 'avg_price' . The initial calculation uses a window function and does not take place until the query is executed. Accuracy: After adding the new 'avg_price' column, it can filter on multiple conditions. All conditions are evaluated at once. This is efficient as it combines all three conditions for filtering into one filter expression which reduces the number of passes made on the data. After using the 'avg_price' column in the filter step, it immediately drops this column to avoid polluting the 'fraudulent_trades' result. Correctness: After adding the new 'avg_price' column, it can filter on multiple conditions using window functions. Also, the price and the stock symbol are also part of the same filter criteria, ensuring the data is filtered as desired. Other Options: Option A : Does not reuse the calculated average price which decreases readability. Option C : Applies filters one after another. Each filter call will perform a full pass on the data, which is inefficient. Also needs to store the new average price in a new column, which will pollute the resulting dataframe. So, it is worse than Option B. Option D : Applies filters one after another and does not reuse the average price, and the filter steps require window function to be evaluated on separate filter operation. It is less efficient than Option B. Option E : Averages price on previously filtered data, which is not according to the requirements.
질문 # 178
You are developing a Snowpark Python stored procedure for processing financial data'. The procedure uses the 'pandas' library for data manipulation and the 'scipy' library for statistical calculations. You want to optimize the execution of the stored procedure to leverage the available resources in your Snowflake environment. Which of the following strategies would be MOST effective in improving the performance of your stored procedure, considering the need to handle large datasets?
정답：A
설명：
Option C is the most effective strategy for improving performance with large datasets. Snowpark's vectorized UDFs allow you to leverage Snowflake's distributed processing capabilities to perform calculations in parallel, avoiding the overhead of transferring data to Pandas. Option B would bring the entire dataset into memory on a single node which defeats the purpose of Snowflakes distributed computing. Option A might help but wouldn't fundamentally address the distribution issue. Option D is a brute-force approach and might help, but vectorized UDFs are more efficient. Option E could work but it requires complicated coding of partitioning logic.
질문 # 179
You have a Snowpark Python stored procedure 'process_data' that takes a Snowpark DataFrame as input, performs several data transformations using functions defined in a separate Python module 'data utils.py', and returns a transformed DataFrame. The 'data utils.py' file is located in your local directory. You want to register this stored procedure so that it can be called from Snowflake. Which of the following code snippets demonstrate(s) the correct way to register the stored procedure, ensuring that the 'data utils.py' module is available within the Snowpark environment? (Select TWO)
정답：B,E
설명：
Option C correctly specifies the 'data_utils.py' file in the 'imports' parameter of the gsproc' decorator, making it available within the Snowpark environment. It also includes re-importing the 'data_utilS package within the function. Option D specifies the file in the 'imports parameter and uses the '_import_' function to load and use the module, which is a valid approach. Option A would error at runtime because "data_utils' won't be found unless it is in the same file as the stored procedure definition or the user has installed the python packages. Option B contains incorrect usage of 'return_type', and and doesn't account for importing 'data_utils.pV. Option E has the same problem as A as the dependent file 'data_utils.py' has not been imported. The 'stage_location' parameter specifies the stage where the Python file should be uploaded. The two correct ways ensure that the data_utils module will be loaded and accessible in the Snowpark environment.
