Which common query problems are identified by the Query Profile? (Choose two.)
Which common query problems are identified by the Query Profile? (Choose two.)
The Query Profile is a tool designed to help identify performance issues in queries. Inefficient pruning and queries too large to fit in memory are common problems that can be identified by the Query Profile. Inefficient pruning occurs when the query scans more data than necessary, which can lead to longer execution times. Queries too large to fit in memory involve intermediate results that exceed the available memory, causing the system to use disk space instead, which can significantly slow down query performance.
Choose two. So best two. From https://docs.snowflake.com/en/user-guide/ui-query-profile. Pruning - information on the effects of table pruning. Spilling — information about disk usage for operations where intermediate results do not fit in memory.

B. Inefficient pruning E. Object does not exist or not authorized Explanation: A Query Profile in Snowflake is designed to provide insights into the performance characteristics of a specific query. Common query problems that can be identified by the Query Profile include: B. Inefficient pruning: It can reveal whether pruning (filtering) of data during query execution is being performed efficiently. Inefficient pruning may result in the query scanning more data than necessary. E. Object does not exist or not authorized: The Query Profile can identify issues related to missing or unauthorized objects in the query. This includes situations where tables or columns referenced in the query do not exist or the user does not have the necessary privileges. Syntax errors (A), ambiguous column names (C), and queries too large to fit in memory (D) are typically identified during the parsing and compilation phases and may not be specifically addressed by the Query Profile.
Object does not exist or not authorized. This will cause a syntax error and never make it to the Profile.
