SnowPro Core Certification — Question 764
What technique does Snowflake use to limit the number of micro-partitions scanned by each query?
Answer options
- A. B-tree
- B. Indexing
- C. Map reduce
- D. Pruning
Correct answer: D
Explanation
The correct answer is D, Pruning, which allows Snowflake to skip over unnecessary micro-partitions based on query filters, thus optimizing performance. The other options, such as B-tree and Indexing, are not utilized by Snowflake in this context, and Map reduce is not relevant to how Snowflake handles data access.
