An Architect is troubleshooting a query with poor performance using the QUERY function. The Architect observes that the COMPILATION_TIME Is greater than the EXECUTION_TIME. What is the reason for…

Question

Options

• AThe query is processing a very large dataset.
• BThe query has overly complex logic.
• CThe query Is queued for execution.
• DThe query Is reading from remote storage

• A
  7% (2)
• B
  48% (14)
• C
  14% (4)
• D
  31% (9)

Explanation

In Snowflake's query profiling (via QUERY_HISTORY), COMPILATION_TIME represents the time spent parsing, optimizing, and generating the execution plan for the query in cloud services. When COMPILATION_TIME exceeds EXECUTION_TIME, it means the query optimizer is spending more effort analyzing complex logic (joins, subqueries, deeply nested CTEs, many predicates) than actually executing the query. Option A (large dataset) would primarily inflate execution time. Option C (queued) would show as queued time, not compilation time. Option D (remote storage) would impact execution time. Overly complex query logic is the primary driver of disproportionately high compilation time.
