First, you’ll explore how to monitor resource usage effectively using account usage and information schema views. Next, you’ll discover techniques to analyze and enhance query performance using Snowflake’s query history. Finally, you’ll understand how to manage resource allocation in virtual ware...
Use Query History in Snowflake to see if any activity is coming across. If there's a problem with the account identifer or password, you won't see any activity. If there's a problem with the default role, you should at least see aUSE WAREHOUSE . . .statement. ...
