Snowflake object tags attach ownership metadata to warehouses, databases, schemas, and other supported objects. The tags can support chargeback and showback reporting.
A tag on a warehouse describes the warehouse and its assigned workload. A tag on a database describes the object queried, not necessarily the team that issued each statement. QUERY_TAG can provide query-level context when sessions or scheduled jobs set it consistently.
Tag values can be joined with metering and query history to aggregate credits by team, cost center, application, or project. Consistent tag keys across warehouses make reports easier to compare.
Tags do not change the credit rate or reduce consumption. They make ownership visible so teams can investigate idle time, queueing, and expensive queries. Snowflake documents object tags and tag references.
