Querying and Performance

Question

You are using Snowsight to monitor the performance of several queries. You notice a query that took significantly longer than expected. Which of the following actions, available directly within the Snowsight Query History Details panel, would BEST help you diagnose the cause of the slow performance?

Options

  • AExamine the SQL text of the query and identify potential areas for optimization based on syntax.
  • BReview the 'Query Profile' to identify specific execution stages that consumed the most resources.
  • CCheck the 'Warehouse Load' graph to see if the warehouse was under heavy load during the
  • DAnalyze the 'Compilation Time' to determine if query compilation contributed significantly to the
  • EDownload the query results to your local machine for further analysis.

Explanation

When diagnosing a slow query in Snowsight's Query History Details panel, the three most useful tools are: (B) the Query Profile, which visualizes execution stages as a tree/graph and highlights which operators consumed the most time, bytes, and rows - making it the primary diagnostic tool for slow queries; (C) the Warehouse Load graph, which shows historical warehouse utilization during the query's execution window, revealing whether resource contention from concurrent queries caused queuing or throttling; and (D) Compilation Time, which is broken out separately and can indicate that complex query logic or insufficient metadata caching added significant overhead before execution even began. Option A (reviewing SQL syntax) is a general optimization approach, not a Snowsight panel feature for diagnosing runtime behavior. Option E (downloading results) provides no diagnostic insight into execution performance.
