D.
Query against the metadata excite
Answers
D.
Query against the metadata excite
Suggested answer: D

Explanation:

Snowflake is designed to optimize query performance by utilizing metadata for certain types of queries. When executing aCOUNTquery, 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 likeFCT_SALESwith 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 aCOUNTquery without the need to perform a full scan.
