How did Snowflake fulfill this query?
A sales table FCT_SALES has 100 million records.
The following Query was executed
SELECT COUNT (1) FROM FCT__SALES;
How did Snowflake fulfill this query?
A . Query against the result set cache
B . Query against a virtual warehouse cache
C . Query against the most-recently created micro-partition
D . Query against the metadata excite
Answer: D
Explanation:
Snowflake is designed to optimize query performance by utilizing metadata for certain types of queries. When executing a COUNT query, Snowflake can often fulfill the request by accessing metadata about the table’s row count, rather than scanning the entire table or micro-partitions. This is particularly efficient for large tables like FCT_SALES with a significant number of records. The metadata layer maintains statistics about the table, including the row count, which enables
Snowflake to quickly return the result of a COUNT query without the need to perform a full scan.
