Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q72-Q77):

NEW QUESTION # 72
You're tasked with loading data representing transactions from a legacy system into Snowflake using Snowpark. The legacy system exports the transaction data as a Python list of tuples, where each tuple contains transaction ID (integer), transaction amount (float), and transaction date (string in 'YYYY-MM-DD' format). The scale of data can be very high and need optimized way to load the data'. Your goal is to create a Snowpark DataFrame from this list of tuples, ensuring the date column is correctly interpreted as a Snowflake Date type. Which of the following approaches would be the most efficient and correct, minimizing data conversion overhead and maximizing Snowpark's capabilities?

A. Create a Snowpark DataFrame directly from the list of tuples using 'session.createDataFrame(datay , relying on automatic schema inference. No need to explicitly convert to 'DateType' as Snowflake will take care of implicit conversion.
B. Create a list of dictionaries from the list of tuples with correct column names, and define a Snowpark schema using 'StructType' and 'StructField', explicitly setting the data type of the date column to 'DateType'. Then, create the Snowpark DataFrame using 'session.createDataFrame(data, schema=schema)'.
C. Convert the list of tuples to a Pandas DataFrame, explicitly specifying the column names and data types (including 'pd.datetime64[ns]' for the date column). Then, create a Snowpark DataFrame from the Pandas DataFrame using 'session.createDataFrame(pandas_df)'.
D. Create a Snowpark DataFrame directly from the list of tuples using 'session.createDataFrame(data)' , relying on automatic schema inference. Then, use function to cast the date column to a DateType.
E. Define a Snowpark schema using 'StructType' and 'StructField' , explicitly setting the data type of the date column to 'DateType'. Then, create the Snowpark DataFrame using 'session.createDataFrame(data,

Answer: E

Explanation:
Option C is the most efficient and correct way. Correctness : Option C explicitly defines the schema, including the 'DateType' for the transaction date. This ensures that Snowflake correctly interprets the date column without requiring any further casting or conversion. Avoids unnecessary string conversion. Efficiency : By defining the schema upfront, you avoid schema inference during dataframe creation, which can be costly for large datasets. This also avoids the cost of explicit casting after dataframe creation (as in Option A). Maximizing Snowpark Capabilities : Directly using Snowpark API to declare data types takes full advantage of Snowpark capabilities. Option A relies on implicit schema inference, which is not optimal in scenarios with specific data type requirements, and it requires an additional step which can be costly for large data. Option B introduces a dependency on Pandas and involves converting the data to a Pandas DataFrame, then to a Snowpark DataFrame, which creates unnecessary overhead and is not the most efficient approach. Option D, although correct, requires you to create a list of dictionaries, which adds an unneeded step in between and may not be optimized. Option E relies on implicit casting; However, this can lead to failure if date format is wrong.

NEW QUESTION # 73
You are working with Snowpark and need to persist the results of a DataFrame 'df to a Snowflake stage named 'my_stage'. You want to achieve the following: 1. Write the data in JSON format. 2. Use snappy compression. 3. Handle potential write errors gracefully. 4. Overwrite any existing files with the same name. Which of the following approaches can achieve these requirements? (Select all that apply)

A. Use compression='snappy', mode='overwrite')' and handle potential exceptions using a 'try-except' block.
B. Define a UDF to write the dataframe into stage along with exception handling logic.
C. Configure the stage 'my_stage' with FILE_FORMAT = (TYPE = 'JSON', COMPRESSION = 'SNAPPY') and then use within a 'try-except' block.
D. Use 'df.write.option('compression', inside a 'try-except block.
E. Wrap the entire write operation in a try-except block and implement retry logic with exponential backoff in case of transient errors.

Answer: A,D,E

Explanation:
Option A directly utilizes the .json(V method for writing JSON files with snappy compression, specifying the 'overwrite' mode, and the 'try-except block adds error handling. Option C specifies the format to JSON using format('json') with snappy compression and specifying the 'overwrite' mode, and using a 'try-except' block for error handling. Option E deals with write errors by wrapping the entire process inside try-except block. Options D is not correct since creating a UDF just for this purpose introduces unnecessary overhead compared to the simple and direct approaches provided by A and C. Option B is incorrect, while configuring the stage with a default file format is useful, it won't apply in this specific write operation using DataFrameWriter. We need to explicitly define format and compression for the operation.

NEW QUESTION # 74
You have a Snowpark DataFrame named 'employee_df in VS Code. You want to define a user-defined function (UDF) in Python that calculates the bonus for each employee based on their salary and performance rating. The UDF should take the salary (SALARY) and performance rating (PERFORMANCE RATING) as inputs and return the bonus amount. Assume you have already established a Snowpark session. Which code snippet accurately defines and registers a UDF named 'calculate_bonus' that can be applied to the 'employee_df DataFrame?

Answer: A,E

Explanation:
Options A and B are both correct methods. Option A defines the Python function and then registers it as a UDF using session.udf.register' . It explicitly specifies the return type, input types, UDF name, and the 'replace=True' option to allow overwriting if the UDF already exists. Option B uses the guff decorator to directly register the function as a UDF, providing a more concise way to define and register UDFs. Option A is also valid as the user defined datatypes and name. Option C requires the snowflake-snowpark-python package (which is already installed via dependencies) and the 'fune argument is redundant. Option D is wrong as would remove the currently configured packages. Option E is incorrect because making the UDF permanent requires additional privileges and setup that aren't covered by default.

NEW QUESTION # 75
You have a Snowpark application that processes sensor data from a large number of devices. You've implemented a scalar UDF in Python to calculate a complex statistical metric for each sensor reading. Initial tests show poor performance. Which of the following strategies would be MOST effective in improving the performance of this application, considering the nature of the computation and the data volume?

A. Rewrite the UDF logic directly in SQL, leveraging Snowflake's built-in functions for statistical calculations.
B. Replace the Python scalar UDF with a Java scalar UDF, as Java typically offers better performance than Python in Snowflake.
C. Implement caching for the UDF results, assuming the statistical metric calculations are frequently repeated for the same sensor readings.
D. Replace the Python scalar UDF with a Python vectorized UDF, ensuring the UDF processes data in batches instead of row-by-row.
E. Increase the warehouse size significantly to provide more resources for the scalar UDF execution.

Answer: D

Explanation:
Vectorized UDFs process data in batches (vectors), significantly reducing the overhead associated with individual row processing, which is the primary bottleneck of scalar UDFs. While increasing warehouse size (C) might provide some improvement, it doesn't address the fundamental inefficiency of scalar processing. Java might be faster (A), but the biggest gain comes from vectorization. Caching (D) is useful for repeated calculations, but doesn't address the inherent UDF overhead if computations are unique. SQL (E) is good, but might not be possible due to the complexity.

NEW QUESTION # 76
You are working with Snowpark DataFrames representing sales transactions. The 'transactions df DataFrame contains recent transactions, while the 'sales_table' in Snowflake holds the historical sales data'. You need to merge the new transactions into the 'sales table', but you want to track which rows were inserted, updated, or left unchanged by the 'merge' operation. How can you capture this information using Snowpark and persist it to a separate table?

A. The merge operation automatically creates a system table or view that logs the details of each row that was inserted, updated, or left unchanged.
B. It's not possible to capture the merge operation details (inserted/updated/unchanged rows) directly using Snowpark alone. You would need to implement custom logic outside of Snowpark to compare the data before and after the merge.
C. You can use the 'returning' clause within the merge statement to retrieve the impacted rows and their change status (INSERTED, UPDATED) and then write this data to a tracking table using 'write.saveAsTable' .
D. You can combine the 'returning' clause along with a stored procedure to retrieve the inserted/updated rows with their status and then use the stored procedure to write to a different tracking table using insert statement.
E. After the merge, query the 'sales_table' and compare it to a copy of the 'sales_table' taken before the merge. Identify inserted rows as those present in the new version but not in the old, and updated rows as those with different values in specific columns between the two versions. This strategy should be implemented with the help of external functions and UDFs, as it is an expensive operation and should not be computed with normal SQL.

Answer: C

Explanation:
The 'returning' clause is a powerful feature of the 'merge' statement in Snowflake SQL. It allows you to capture the rows that were affected by the merge operation, along with details about the type of change (INSERTED, UPDATED, DELETED). In Snowpark, you can leverage this by including a 'returning' clause in your 'merge' statement and then use the returned DataFrame to write the data to a tracking table. This provides a direct and efficient way to monitor the impact of your merge operations. Therefore the correct answer is B.
