質問 # 363
An external stage many_stage contains many directories including one, app_files that contains CSV files How can all the CSV files from this directory be moved into table my_table without scanning files that are not needed?
正解：C
質問 # 364
Which Snowflake feature enables loading data from cloud storage as soon as files are available in a stage?
正解：B
質問 # 365
Which strategy for optimizing virtual warehouse performance should be used to speed the execution of a very large query?
正解：C
質問 # 366
What persistent data structures are used by the search optimization service to improve the performance of point lookups?
正解：B
解説：
The search optimization service in Snowflake uses persistent data structures known as search access paths to improve the performance of point lookups. These structures enable efficient retrieval of data by reducing the amount of data scanned during queries.
Search Access Paths:
Search access paths are special indexing structures maintained by the search optimization service.
They store metadata about the distribution of data within tables, enabling faster lookups for specific values.
Point Lookups:
Point lookups involve searching for a specific value within a column.
By leveraging search access paths, Snowflake can quickly locate the exact micro-partition containing the value, minimizing the amount of data scanned.
Performance Improvement:
The use of search access paths significantly reduces query execution time for point lookups.
This is especially beneficial for large tables where scanning all micro-partitions would be computationally expensive.

質問 # 367
How can a user validate if a micro-partition is pruning efficiently?
正解：B
解説：
The correct answer is A. By inspecting the statistics pane in the Query Profile .
The Query Profile provides execution details for a query. To evaluate micro-partition pruning, users can inspect scan statistics, including partitions scanned versus total partitions. This helps determine whether Snowflake is efficiently skipping unnecessary micro-partitions.
Why A is correct:
The Query Profile statistics pane can show how many partitions were scanned and how many total partitions existed. Efficient pruning means Snowflake scanned only a small portion of the total relevant micro-partitions.
Example interpretation:
Partitions scanned: 100
Partitions total: 10,000
This indicates strong pruning because Snowflake skipped most micro-partitions.
Why the other options are incorrect:
B). Query details in Snowsight provide useful metadata such as duration, warehouse, and query text, but the Query Profile statistics pane is the best place to validate pruning efficiency.
C). SYSTEM$CLUSTERING_INFORMATION() gives clustering information for a table, such as clustering depth and overlap, but it does not directly show whether a specific query pruned efficiently.
D). INFORMATION_SCHEMA.TABLES provides table metadata, not query-level partition pruning details.
Official Snowflake documentation reference:
Snowflake documentation explains that Query Profile provides detailed execution information, including table scan statistics such as partitions scanned and partitions total. These statistics help validate pruning effectiveness.
