| # **what?** | |
| # Compares the schema of the dbt version of the given ref vs | |
| # the latest official schema releases found in schemas.getdbt.com. | |
| # If there are differences, the workflow will fail and upload the | |
| # diff as an artifact. The metadata team should be alerted to the change. | |
| # | |
| # **why?** | |
| # Reaction work may need to be done if artifact schema changes | |
| # occur so we want to proactively alert to it. | |
| # | |
| # **when?** | |
| # On pushes to `develop` and release branches. Manual runs are also enabled. | |
