질문 # 244
You are tasked with optimizing a Snowpark Python application that performs complex data transformations on a large dataset. The application's performance is currently bottlenecked by the data transfer between Snowflake and the client machine running the Python code. Which of the following strategies can effectively minimize data transfer and improve performance?
정답：A
설명：
Snowpark's lazy evaluation, data filtering/aggregation within Snowflake, and vectorized UDFs are crucial for minimizing data transfer. Lazy evaluation ensures that data is only transferred when needed. Pushing down operations like filtering and aggregation to Snowflake reduces the amount of data transferred. Vectorized UDFs allow UDFs to operate on batches of data, improving performance. Fetching the entire dataset into a Pandas DataFrame (C) exacerbates the data transfer bottleneck. Disabling lazy evaluation (D) is counterproductive.
질문 # 245
Consider the following Snowflake SQL statement intended to modify the properties of a Snowpark-optimized virtual warehouse named
'SNOWPARK_WH':
Which of the following statements accurately describe the expected outcome of executing this SQL statement?
정답：B,D
설명：
The 'ALTER WAREHOUSE statement is valid and will modify the specified properties. However, the user executing the statement must have the 'MODIFY privilege on the warehouse. The 'SCALING_POLICY parameter can be set for Snowpark-optimized warehouses, just like standard warehouses. All options can be specified in a single ALTER statement provided correct synax, the WAREHOUSE has been created and current User have correct privileges.
질문 # 246
You are tasked with creating a Snowpark DataFrame from a complex JSON structure stored in a VARIANT column named 'payload' within a table called 'events'. The 'payload' contains nested objects and arrays, and you need to extract specific fields into separate columns of the DataFrame. You need to extract the 'event_id' (INT) from the top level of the JSON, the 'user _ id' (INT) from the 'user' object nested within the 'payload' , and the first element of the 'tags' array (VARCHAR) also nested within the 'payload'. Which of the following code snippets correctly defines the schema using 'StructType' and 'StructField' and applies it during DataFrame creation assuming events table contains multiple rows?
정답：B
설명：
Option B extracts the necessary data and creates schema separately. Option A cannot chain the schema to after select operatiom Option C defines payload as VariantType, which is already there. option D has with_schema function which does not exist in current snowflake version. Option E tries to apply schema before select statement which is logically wrong.
질문 # 247
A Snowpark application processes streaming data from Kafka, performing complex windowing aggregations. The application is configured with auto-scaling enabled for the virtual warehouse. During peak hours, the application exhibits high latency despite the warehouse scaling up. Upon investigation, you observe sustained high CPU utilization on the single active warehouse. Which actions, alone or in combination, would MOST effectively improve performance while minimizing cost?
정답：B,E
설명：
Optimizing the Snowpark code (Option B) reduces the overall CPU load, while repartitioning the data (Option C) distributes the work more evenly across multiple clusters, reducing hotspots and enabling parallel processing. Increasing MAX_CLUSTER_COUNT (Option A) only helps if the workload is already evenly distributed. Increasing MIN_CLUSTER COUNT (Option D) may add to cost without addressing the underlying code issues or data skew. Decreasing SCALING_POLICY (Option E) may help with responsiveness but isn't a fundamental solution.
질문 # 248
Consider a JSON structure representing product information, where prices are stored as strings due to inconsistent data quality. You need to calculate the average price of products. However, some price strings contain non-numeric characters (e.g., '$', commas). Which of the following approaches, using Snowpark DataFrame operations, is the MOST robust and efficient way to clean and cast the price data to a numeric type for accurate average calculation?
정답：E
설명：
Option D is the most robust. It uses 'regexp_replace' to remove '$' and commas from the price string and then uses which handles cases where the cleaned string still cannot be converted to a number gracefully (returning NULL instead of throwing an error). Then computes the average on this column. Option A would fail in some cases as it cast the string to float directly, so some string format won't work, it's better using Option B would throw error while casting when the number is not in float format. Option C would throw error while casting as to_number need to be called with a format to work. Option E would raise conversion error because return variant and not numeric type to be cast to float.
