COF-C02 Question #504: Real Exam Question with Answer & Explanation
The correct answer is B: II maintains a persistent data structure that keeps track of the values of the table's columns m each. The search optimization service in Snowflake enhances query performance by maintaining a persistent data structure. This structure indexes the values of table columns across micro- partitions, allowing Snowflake to quickly identify which micro-partitions contain relevant data for
Question
How does the search optimization service help Snowflake users improve query performance?
Options
- AIt scans the micro-partitions based on the joins used in the queries and scans only join columns.
- BII maintains a persistent data structure that keeps track of the values of the table's columns m each
- CIt scans the local disk cache to avoid scans on the tables used in the Query.
- DIt keeps track of running queries and their results and saves those extra scans on the table.
Explanation
The search optimization service in Snowflake enhances query performance by maintaining a persistent data structure. This structure indexes the values of table columns across micro- partitions, allowing Snowflake to quickly identify which micro-partitions contain relevant data for a query. By efficiently narrowing down the search space, this service reduces the amount of data scanned during query execution, leading to faster response times and more efficient use of
