When optimizing query performance in Snowflake, what benefits does result caching provide?

Question

Options

• AImproves schema changes management
• BRestricts query optimization
• CLimits data access for specific user roles
• DSpeeds up query execution by storing intermediate results

• A
  5% (1)
• C
  5% (1)
• D
  89% (17)

Explanation

Result caching in Snowflake stores the output of previously executed queries so that identical subsequent queries can return results instantly without re-executing against the underlying data - directly speeding up query execution, making D correct. Options A and B are wrong because result caching has nothing to do with schema management or restricting optimization; in fact, it enhances optimization rather than limiting it. Option C describes role-based access control (RBAC), a separate security feature entirely unrelated to caching mechanics.

Memory tip: Think of result caching like a calculator's "Ans" button - it holds the last answer so you don't have to recompute. In Snowflake, cached results are reused for up to 24 hours as long as the underlying data hasn't changed, bypassing the virtual warehouse entirely.
