What is the relationship between a Query Profile and a virtual warehouse?

The correct answer is A. A Query Profile can help users right-size virtual warehouses. A Query Profile in Snowflake provides detailed execution statistics for a query, including processing time, bytes scanned, rows processed, and which nodes consumed the most resources. By analyzing this data, users can identify whether a warehouse is undersized (causing spilling…

Question

What is the relationship between a Query Profile and a virtual warehouse?

Options

  • AA Query Profile can help users right-size virtual warehouses.
  • BA Query Profile defines the hardware specifications of the virtual warehouse.
  • CA Query Profile can help determine the number of virtual warehouses available.
  • DA Query Profile automatically scales the virtual warehouse based on the query complexity.

Explanation

A Query Profile in Snowflake provides detailed execution statistics for a query, including processing time, bytes scanned, rows processed, and which nodes consumed the most resources. By analyzing this data, users can identify whether a warehouse is undersized (causing spilling to disk or long queue times) or oversized (idle nodes, low utilization). This makes the Query Profile a practical tool for right-sizing virtual warehouses - choosing the appropriate warehouse size (XS, S, M, L, etc.) for a given workload. It does not define hardware specs (B), determine the count of available warehouses (C), or automatically trigger auto-scaling (D).
