Snowflake's "query tagging" is a feature that enables you to include custom labels with your SQL queries. You can apply tag to individual queries or sets of queries, aiding in their organization and categorization for the purpose of tracking and reporting.
For example, you might tag queries with information about the department or team responsible for them, the purpose of the query, or the project it's related to. By tagging queries with relevant information, you can more easily monitor and analyze query performance.
