Databricks tags attach ownership metadata to workspaces, clusters, jobs, SQL warehouses, and other resources. Billing records can use tags to attribute usage to teams, projects, and environments.
A tag does not change the DBU rate or reduce consumption. It makes shared usage visible. Consistent keys such as team, environment, and cost_center support group-by reports across workspaces.
Combine tags with system billing tables and cloud-provider records. A DBU-only report omits the infrastructure charge for classic compute. Review tag coverage when a new cluster or job is created, because untagged usage cannot be assigned reliably after the fact.
