The Query Profile in Snowflake provides detailed insights into the execution of a query. It helps in troubleshooting performance issues by showing the steps of the query execution and the resources consumed.
One of the key aspects it reveals is whether the virtual warehouse memory was sufficient for the query.
* Access Query Profile:Navigate to the Query History page and select the query you want to analyze.
* Examine Query Execution Steps:The Query Profile displays the different stages of the query execution, including the time taken and resources used at each step.
* Identify Memory Issues:Look for indicators of memory issues, such as spilling to disk or memory errors, which suggest that the virtual warehouse memory might be too small.

Running EXPLAIN and SHOW commands, as well as running a custom query, consume virtual warehouse credits in the Snowflake environment. These activities require computational resources, and therefore, credits are used to account for the usage of these resources. References: [COF-C02] SnowPro Core Certification Exam Study Guide
