Answer: SET spark.databricks.delta.retentionDurationCheck.enabled = false
By default, the `VACUUM` command in Databricks prevents the deletion of files less than 7 days old to ensure no long-running operations are referencing them. If you're certain no operations (like insert, upsert, delete, or optimize) are being performed on the table, you can disable this safety check by setting `spark.databricks.delta.retentionDurationCheck.enabled` to false.
